Why is being a 'grace-made man' important for Christians?

The concept of a 'grace-made man' is crucial because it distinguishes true believers from those who are merely self-made or self-righteous. Paul emphasizes in 1 Corinthians 15:10 that he is what he is by God's grace. This underscores that a true Christian identity is rooted in humility and understanding one's dependence on God's grace. It is through grace that believers receive life, become new creations, and ultimately reflect God's glory. Thus, Christians should strive to embody this grace that leads to genuine faith and obedience.
