God Wants to Teach us Himself
Most professing Christians who go to "church", rely on the preacher to teach them the way of salvation. Despite his many years in College obtaining his training in divinity, is he capable of doing this? Does he preach Christ, and Him risen, or does he preach denominationism (that which he is told to preach by the denomination to which he owes loyalty and from which he receives, indirectly, his salary). 

However, we don't need a preacher, teacher, Pastor or any other human being to teach us God's will in our lives. We have the inspired word of the real, caring, Living, God to do this for us. 

I have heard or read of people in authority say: 
The Bible isn't really God's word, it's just a jumble of works by different people that anyway have changed in meaning over the centuries. 
There are so many contradictions in the Bible, I don't understand what's going on. 
You need someone to interpret the Bible for you. 
Don't spend so much time in the Bible, listen to the Holy Spirit. 

Nevertheless, let's see what God has to say about the matter. 

Firstly, about the Bible: 
Every word of God is pure: he is a shield unto them that put their trust in him. Add thou not unto his words, lest he reprove thee, and thou be found a liar. 
(Proverbs 30:5-6) 
Sanctify them through thy truth: thy word is truth. 
(John 17:17) 

And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works. 
(2 Timothy 3:15-17)
So, now we know what the truth is, we have the Bible as a sure foundation to search for His will in our lives: 
My son, if thou wilt receive my words, and hide my commandments with thee; So that thou incline thine ear unto wisdom, and apply thine heart to understanding; Yea, if thou criest after knowledge, and liftest up thy voice for understanding; If thou seekest her as silver, and searchest for her as for hid treasures; Then shalt thou understand the fear of the LORD, and find the knowledge of God. For the LORD giveth wisdom: out of his mouth cometh knowledge and understanding. He layeth up sound wisdom for the righteous: he is a buckler to them that walk uprightly. He keepeth the paths of judgment, and preserveth the way of his saints. Then shalt thou understand righteousness, and judgment, and equity; yea, every good path. When wisdom entereth into thine heart, and knowledge is pleasant unto thy soul; Discretion shall preserve thee, understanding shall keep thee: To deliver thee from the way of the evil man, from the man that speaketh froward things; 
(Proverbs 2:1-12) 

Receive, I pray thee, the law from his mouth, and lay up his words in thine heart. 
(Job 22:22) 

O my God, I trust in thee: let me not be ashamed, let not mine enemies triumph over me. Yea, let none that wait on thee be ashamed: let them be ashamed which transgress without cause. Shew me thy ways, O LORD; teach me thy paths. Lead me in thy truth, and teach me: for thou art the God of my salvation; on thee do I wait all the day. Remember, O LORD, thy tender mercies and thy lovingkindnesses; for they have been ever of old. Remember not the sins of my youth, nor my transgressions: according to thy mercy remember thou me for thy goodness' sake, O LORD. Good and upright is the LORD: therefore will he teach sinners in the way. The meek will he guide in judgment: and the meek will he teach his way. All the paths of the LORD are mercy and truth unto such as keep his covenant and his testimonies. For thy name's sake, O LORD, pardon mine iniquity; for it is great. What man is he that feareth the LORD? him shall he teach in the way that he shall choose. His soul shall dwell at ease; and his seed shall inherit the earth. The secret of the LORD is with them that fear him; and he will shew them his covenant. 
(Psalms 25:2-14)
God wants to teach us Himself, through His word and His Holy Spirit: 
I will instruct thee and teach thee in the way which thou shalt go: I will guide thee with mine eye. 
(Psalms 32:8) 

Turn you at my reproof: behold, I will pour out my spirit unto you, I will make known my words unto you. 
(Proverbs 1:23) 

And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem. 
(Isaiah 2:3) 

And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more. 
(Jeremiah 31:34) 

It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me. 
(John 6:45) 

But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. 
(John 14:26) 

But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. 
(1 Corinthians 2:10) 

But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another. 
(1 Thessalonians 4:9) 

And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest. 
(Hebrews 8:11) 

But ye have an unction from the Holy One, and ye know all things. 
(1 John 2:20) 

But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him. 
(1 John 2:27) 

But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him
(Hebrews 11:6)
