The Bible plainly and repeatedly warns believers not to put their trust in men. In addition to this truth, men are not to trust in themselves. As today's passage shows, sometimes God allows circumstances to come into our lives in order to teach us not to trust in ourselves. If any mere mortal could stake a claim to self-trust, it would have been the apostle Paul. He was “circumcised the eighth day,” “an Hebrew of the Hebrews,” and “a Pharisee” (Philippians 3:5). In spite of this, Paul knew these attributes were not sufficient to trust for eternal life. In fact, he counted these things but dung, that he may win Christ (Philippians 3:8). If Paul understood that he could not put his trust in himself or his accomplishments, everyone else should realize that his or her ability or merits are not worthy of trust.
Romans 3:4 says, “let God be true, but every man a liar.” Perhaps this truth serves as the foundational reason why God warned believers not to place their trust in man. Though the primary reason, it is not the only reason. In Psalm 146:3 the Lord warns, “Put not your trust in princes, nor in the son of man, in whom there is no help.” The real needs of mankind cannot be satisfied by man, even the best of men. Those who put their trust in man do so in disobedience to the Lord which results in their own personal harm. Psalm 118:8-9 twice stresses that “It is better to trust in the LORD.” An improper trust in man is, in many ways, a departure from the Lord (Jeremiah 17:5).
The Bible points to the unsaved man as an enemy of God (Romans 5:10). Fortunately, those who have trusted Christ as Saviour have been reconciled to God through the blood of Jesus Christ (Romans 5:10; 2 Corinthians 5:18). This reconciliation transforms the enemies of God into His ambassadors (2 Corinthians 5:20). What a wonderful salvation! But there is more! The Lord Jesus has given the ministry of reconciliation to all those who have been reconciled. As such, we are to submit ourselves to the work of telling others how they too can be reconciled to God. Paul understood this and declared that he was a “debtor both to the Greeks, and to the Barbarians; both to the wise, and to the unwise” (Romans 1:14).
