Ephesians 4:1 Grit vs. Grace

After overflowing affirmations throughout chapters 1-3, Paul now turns to the imperative of the Christian, that is, "live a life worthy of the calling to which you have been called." How does one accomplish such a high calling? Many try it through grit, but the real answer lies in grace.

As a prisoner for the Lord, then, I urge you to live a life worthy of the calling you have received.
— Ephesians 4:1
