For if they fall, the one will lift up his fellow: but woe to him [that is] alone when he falleth; for [he hath] not another to help him up. Again, if two lie together, then they have heat: but how can one be warm [alone]? And if one prevail against him, two shall withstand him; and a threefold cord is not quickly broken. –Ecclesiastes 4:10-12
Mat 18:20 For where two or three are gathered together in my name, there am I in the midst of them.
Friends, we need to watch who we allow to have that close relationship with and fortunately God gives us a very good guideline: Our friends should be other Christians. Jesus said where two or three are gathered in my name I am there in the midst. And that third person in the three strand cord of the Christian friendship is Jesus. When I am fellowshipping with my friends having a good time or giving and receiving council it is good because we have that common bond.
Pro 27:17 Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.
Why not be friends with everybody? Well, your friends, if you believe it or not, have and influence over you. Iron sharpens iron, but the anvil wears out the hammer. If you both are coming from the same frame of reference you can find yourself being brought down by even the best intended friends. I Remember one broken hearted mother whom I knew who had devotions every day, sent her son to a Christian school, even a Christian college who saw her son drawn away then down into sin by the influence of ungodly friends. We need go no further than the Bible for an example:
Seven years old was Jehoash when he began to reign… And Jehoash did that which was right in the sight of the LORD all his days wherein Jehoiada the priest instructed him. –2 Kings 11:21 and 12:2.
Jehoash did right while being instructed by his priest but when he died he began listening to his friends and things went downhill fast he left the true God and served idols, kill the son of he mentor when he did not like the message (2 Ch. 24:22) and God delivered him into the hands of the Syrians for Judgment (v.24). We need to watch who we take council with and allow ourselves to be friends with.
This does not me we do not love the lost but we are admonished “friendship with the world is eminty with God” (James 4:4) so rather we are to be all things to all men” (1 Corinthians 9:22) not to seem weak or wishy-washy but to show them love and compassion to open the door for them to be saved.
