What does the Bible say about trusting in God instead of man?

In Psalm 146, we see a clear message that believers should not put their trust in princes or humans, for they cannot save us. This scripture highlights the frailty of man, stating that his breath goes forth, and in that very day, his thoughts perish (Psalm 146:3-4). Instead, the 'happiest' individuals are those who have the God of Jacob as their help and hope (Psalm 146:5). This refers to a God who is immutable, omnipotent, and sovereign, capable of providing true help and salvation that man simply cannot offer. As Isaiah notes, man is ephemeral, 'his breath is in his nostrils' (Isaiah 2:22), reminding us that our trust should be placed solely in God, who is eternal and steadfast.
