Here is the text of the prophecy of Jeremiah, where we find the answer to the question:
Thus says the LORD, ”Cursed is the man who trusts in mankind and makes flesh his strength, and whose heart turns away from the LORD. For he will be like a bush in the desert and will not see when prosperity comes, but will live in stony wastes in the wilderness, a land of salt without inhabitant. Blessed is the man who trusts in the LORD and whose trust is the LORD. For he will be like a tree planted by the water, that extends its roots by a stream and will not fear when the heat comes; but its leaves will be green, and it will not be anxious in a year of drought nor cease to yield fruit. (Jeremiah 17:5-8)(NASB)
God’s Word does not say that we must not trust each other in everyday life, but that it is a sin to trust in man rather than in God. People are limited and they are not masters of any situation. Therefore, in difficult situations of life, in fact in any circumstances, we shall appeal to God and not trust in any man more than in God.
