How do we know the doctrine of denying ourselves is true?

The notion of self-denial is not merely a suggestion but a command from Jesus, found in Luke 9:23, where He states, 'If anyone would come after me, let him deny himself and take up his cross daily and follow me.' This doctrine is foundational to the Christian faith, validating the idea that a true follower of Christ must prioritize God's will over personal desires. The call to self-denial signifies turning away from worldly temptations and aligning one's life with God's purposes, demonstrating commitment to Christ even at great personal cost.
