Why is trusting in God instead of men important for Christians?

Scripture cautions against placing trust in earthly rulers and men, as articulated in Psalm 146:3-4, 'Put not your trust in princes, nor in the son of man, in whom there is no help.' The frailty of human beings is highlighted, showing that their lives are transient and ultimately devoid of eternal value or salvation. Conversely, God is eternal and perfect in power, capable of providing true help and salvation. This distinction encourages believers to lean upon God, whose promises endure forever and whose salvation through Christ is assured and unwavering.
