What is will worship and why is it considered folly?

Will worship refers to the act of putting confidence in one's own ability or will to achieve salvation. This is seen as folly because it directly opposes the Biblical teaching that salvation is accomplished solely by God's will (Isaiah 14:12-15). In Exodus 15:9, the enemies declared, 'I will,' which reflects the natural man's inclination to rely on self rather than submitting to God's sovereignty. This self-reliance is ultimately fruitless and leads to spiritual death, as salvation cannot be earned through human willpower. Instead, Christians are called to trust in Christ's finished work, acknowledging that He is the true source of redemption and righteousness.
