Trust not in Man!

"Thus says the Lord : “Cursed is the man who trusts in man And makes flesh his strength, Whose heart departs from the Lord." (Jeremiah 17:5 NKJV)
Friendship that consists in mutual trust and support among humans is God's idea for He created man with the  capacity to love and be loved, to care and be cared for. Yet He did not intend that human relationship will take His place on the thrones of our hearts.
The man who puts his confidence in another man does not have a better lot than the pilot who thinks that spider web could give a safe support to his aircraft in the face of looming crash.
Most of the friendship you will enter in your lifetime will not last for more than 3-5 years on the average. Wont it be wise therefore not to base your life on such temporary phenomenon. 
The attitude of reposing confidence in man usually creeps into the heart subtly and remians there for a long time unnoticed by its bearer. In most cases, circumstances and happenings have been the revealer of this "malady" of the heart - you really don't know how much confidence you have in people until they disappoint you; though they did not actually disappointment you, they are only being human, because human beings do not have the capacity to be the object of your trust like God is. Psalm 118:8-9 comes in handy: "It  is better to trust in the Lord Than to put confidence in man. It  is better to trust in the Lord Than to put confidence in princes."
You speak of a close friend who back-stabbed you; you describe the deep hurt of betrayal; you vowed never to forgive the man that let you down when you least expected, you bear the pain of human disappointments, you have become a victim of failed promises: the impact of their infidelity is so great that up till now, you couldnt put the broken pieces of your life together. 
Do you not know that the more you rest on a man, the more hurting you will be when he fails you; can a man bear his own "weight" without God, talkless of bearing that of another? Can you not see the folly of giving to man what ONLY God deserves?
Its only a matter of time (at most 2 years), you will get to discover that the man you call your "brother from another mother" is just as fickle as any other person you have met. I have not by this suggested that you should live in suspicions and hold every man in doubt; not at all. Am only saying that you should trust humans ONLY within the limit allowed by God; because any step beyond that boundry will only set you up for a crash. Jesus our Lord exemplified this according to John 2:24-25 "But Jesus did not commit Himself to them, because He knew all men,  and had no need that anyone should testify of man, for He knew what was in man."
The mockery of His kinsmen, the turning back of His disciples (John 6), the evil plot of the Jews against Him; the betrayal by Judas and the denial  by Peter, the doubts of brother Thomas all put together  were not enough to hurt Him or make Him resentful: He remained unruffled, He did not loose His peace, He still achieved His purpose; the will of the Lord propsered in His hands in spite of the odds from men.
"Wait on the Lord ; Be of good courage, And He shall strengthen your heart; Wait, I say, on the Lord !" (Psalms 27:14 NKJV)
