Faith as a Mustard Seed 
Those of us who have ever been to church have probably at some stage heard of the story told by Jesus of Nazareth of "faith as of a mustard seed". While the story had interesting repercussions, possibly leading to thoughts of fantasy movies such as the doings of Harry Potter, the reality of the power of the statement failed to register until one becomes reborn of the Spirit of God - this in itself being an act of faith; a reaction of the human soul to a totally unexplainable, supernatural occurrence by an unseen yet readily perceived spiritual power. This spiritual power can have evil connotations or righteous, depending on the will, the choice, of the soul of the person concerned. 
Satan, who is the god of this world as previously explained1 is very powerful, very evil and all around us. 
However, the God of Creation, the Triune God, is omnipotent (all powerful) and if we call on Him in righteousness and faith, He shall answer. In Love. 
Then said he unto the disciples, It is impossible but that offences will come: but woe unto him, through whom they come! It were better for him that a millstone were hanged about his neck, and he cast into the sea, than that he should offend one of these little ones. Take heed to yourselves: If thy brother trespass against thee, rebuke him; and if he repent, forgive him. And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him. And the apostles said unto the Lord, Increase our faith. And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you. But which of you, having a servant plowing or feeding cattle, will say unto him by and by, when he is come from the field, Go and sit down to meat? And will not rather say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink? Doth he thank that servant because he did the things that were commanded him? I trow not. So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do. 
(Luke 17:1-10)
Here is a most wonderful promise of God: 
Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? Then Peter said unto them, Repent, and be baptised every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call. And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation. Then they that gladly received his word were baptised: and the same day there were added unto them about three thousand souls. 
(Acts 2:37-41)
You see, you have the potency of the power inside you. You just have to believe this. 
And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation: Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you. 
(Luke 17:20-21)
The Kingdom grows in you as your faith grows: 
And he said, Whereunto shall we liken the kingdom of God? or with what comparison shall we compare it? It is like a grain of mustard seed, which, when it is sown in the earth, is less than all the seeds that be in the earth: But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it. And with many such parables spake he the word unto them, as they were able to hear it. But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples. 
(Mark 4:30-34)
There are many of you out there, in the bundu of the Karoo, the outback of Australia, the desolate winters of the steppes of Canada and Russia, etc., where the nearest neighbour is many kilometres away an your only source of two way communication is either the telephone or the radio. 
You may feel that you are at a disadvantage compared to City dwellers concerning having fellowship one with another. Please understand that if you are a child of God, you are where you should be, placed where you are for your heavenly Father's purpose and glory2
Your very isolation works God's purpose as you use your leisure time to study His word and begin noticing His Hand in His Creation around you. 
As your Spiritual mustard seed grows into a bigger and bigger plant, you will feel the need to share the good things with others in ways that shall be revealed to you. 
All you need to do is be ready and willing to be obedient to the unmistakable Spiritual call that shall come. 
Your reward will be great in heaven 
It is not necessary for you to gather together physically, you just need a line of communication to the soul of someone, whether it's your spouse, children, parents, servants, fellow workers, boss, or someone far away that you can communicate with. 
You may be physically disabled.
Who can you reach with the good news?2 
For where two or three are gathered together in my name, there am I in the midst of them. 
(Matthew 18:20)
You must keep the lines of communication open so that the Holy Spirit can bless others: 
Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. 
(Hebrews 10:23-25)
You shall be rewarded for your faithfulness and perseverance3
Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord; And he shall send Jesus Christ, which before was preached unto you: Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began. 
(Acts 3:19-21)
Here's a fable as an illustration:
A very famous preacher, evangelist and teacher who caused hundreds to come to Christ, died and eventually came face to face with Jesus Christ at the time of receiving rewards for faithfulness. 
As he stood waiting, he witnessed an old lady receiving blessing upon blessing, crown after crown, reward upon reward, and he thought "she couldn't have done what I've done, I'm going to receive plenty." 
When his turn came Jesus said to him "I know your thoughts, but your rewards will not be as many as hers because I gave you an anointing to save thousands out of the hands of Satan, but you only saved a few hundred."
