The Church of Christ Jesus 
The last composition* explained the difference between the apostate church and the Church of Christ Jesus, not so. 
If you, reborn Christian, had a dispute with a church-goer on the issue, would you be able to present the evidence of what a Christian is? 
Or, many unbelievers bring up the evolution theory etc., but their favourite seems to be "If God were so righteous, why would He allow so many billions of people to die in ignorance of Him and end up in hell." 
Would you be able to answer them? 
Paul had the same problems, but even more so, because his enquirers had no Scriptures to help them with. We are so privileged in this respect and so are the church-goers. 
Not all of us have been given a teaching gift and anyway even though we have the Holy Spirit to guide us, we might be under the influence of worldly things to such an extent that we have quenched most of the evidence of His presence in our lives. 
It is doubtful if anyone has ever won an argument where the two parties heatedly disagree with each other; but it may be that the Lord places someone in your way that needs conviction and in that context the following Scriptures shall be of use to you. 
Firstly we must remember that the Holy Spirit is there to help us, if we only allow Him to: 
And when they bring you unto the synagogues, and unto magistrates, and powers, take ye no thought how or what thing ye shall answer, or what ye shall say: For the Holy Ghost shall teach you in the same hour what ye ought to say. 
Luke 12:11-12)
Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you. 
(Philippians 3:15)
But ye have an unction from the Holy One, and ye know all things. 
(1 John 2:20)
Secondly, there must be no disagreement about who God is. The Creator. 
What shall we say then? Is there unrighteousness with God? God forbid. For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy. For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth. Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth. Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will? Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus? Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour? What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction: And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory, Even us, whom he hath called, not of the Jews only, but also of the Gentiles? 
(Romans 9:14-24)
Also it must be affirmed that this is done in the name of Him through whom we come to the throne of grace - the Lord Jesus Christ. We must therefore accept the following Scriptures as a basis for the discussion: 
And Jesus called a little child unto him, and set him in the midst of them, And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven. 
(Matthew 18:2-4)
But when Jesus saw it, he was much displeased, and said unto them, Suffer the little children to come unto me, and forbid them not: for of such is the kingdom of God. Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall not enter therein. 
(Mark 10:14-15)
And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that there should be time no longer: But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets. 
(Revelation 10:6-7)

The epistle to the Ephesians is a passage of Scripture (holy writing) addressed to true believers, the Church of Christ Jesus, so amongst its pages we shall find the answer for those disputing with you and who might be searching for an answer in their hearts to the most important question of all time. 
For this cause I Paul, the prisoner of Jesus Christ for you Gentiles, If ye have heard of the dispensation of the grace of God which is given me to you-ward: How that by revelation he made known unto me the mystery; (as I wrote afore in few words, Whereby, when ye read, ye may understand my knowledge in the mystery of Christ) Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; That the Gentiles should be fellow-heirs, and of the same body, and partakers of his promise in Christ by the gospel: Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power. Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ: To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God, According to the eternal purpose which he purposed in Christ Jesus our Lord: In whom we have boldness and access with confidence by the faith of him. Wherefore I desire that ye faint not at my tribulations for you, which is your glory. For this cause I bow my knees unto the Father of our Lord Jesus Christ, Of whom the whole family in heaven and earth is named, That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man; That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love, May be able to comprehend with all saints what is the breadth, and length, and depth, and height; And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God. Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen. 
(Ephesians 3:1-21)
And you hath he quickened, who were dead in trespasses and sins; Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others. But God, who is rich in mercy, for his great love wherewith he loved us, Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;) And hath raised us up together, and made us sit together in heavenly places in Christ Jesus: That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast. For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands; That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. 
(Ephesians 2:1-13)
If after this, the person with whom you are having a discussion professes an interest in his/her future, read the whole of Ephesians together carefully, taking a verse or two at a time and mulling over the meaning. If enthusiasm develops, purchase an inexpensive King James Bible for that person and make a point of studying it together on a regular basis. Start with the gospel of John and then the rest of the New Testament. It will amaze you how much the Holy Spirit shall teach you as well. 
For example, let's look at the following passage: 
For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church: For we are members of his body, of his flesh, and of his bones. For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. This is a great mystery: but I speak concerning Christ and the church. 
(Ephesians 5:29-32)
Think about this.
Do we each feel that we are members of a family?
Forgetting about the other family members (Christians) for a moment, how real is the family head and how intimate are we with Him? 
Children, obey your parents in the Lord: for this is right. Honour thy father and mother; (which is the first commandment with promise;) That it may be well with thee, and thou mayest live long on the earth. 
(Ephesians 6:1-3)
Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are. Let no man deceive himself. If any man among you seemeth to be wise in this world, let him become a fool, that he may be wise. For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness. And again, The Lord knoweth the thoughts of the wise, that they are vain. Therefore let no man glory in men. For all things are yours; Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are yours; And ye are Christ's; and Christ is God's. 
(1 Corinthians 3:16-23)
Wherefore we labour, that, whether present or absent, we may be accepted of him. For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad. Knowing therefore the terror of the Lord, we persuade men; but we are made manifest unto God; and I trust also are made manifest in your consciences. For we commend not ourselves again unto you, but give you occasion to glory on our behalf, that ye may have somewhat to answer them which glory in appearance, and not in heart. For whether we be beside ourselves, it is to God: or whether we be sober, it is for your cause. For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead: And that he died for all, that they which live should not henceforth live unto themselves, but unto him which died for them, and rose again. Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we him no more. Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation; 
(2 Corinthians 5:9-18)
Concerning the family, how do we each apply our Christian lives to the members thereof? 
Servants, be obedient to them that are your masters according to the flesh, with fear and trembling, in singleness of your heart, as unto Christ; Not with eyeservice, as menpleasers; but as the servants of Christ, doing the will of God from the heart; With good will doing service, as to the Lord, and not to men: Knowing that whatsoever good thing any man doeth, the same shall he receive of the Lord, whether he be bond or free. And, ye masters, do the same things unto them, forbearing threatening: knowing that your Master also is in heaven; neither is there respect of persons with him. 
(Ephesians 6:5-9)
May God, who is love, bless and keep you and those with whom you have fellowship. 
And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life. 
(1 John 5:20)
