not rendering evil for evil, or reviling for reviling; but instead blessing; knowing that to this were you called, that you may inherit a blessing.
The ground for the Christian’s good will to others, even our enemies, is the mercy we receive from God. God blessed us when we were His enemies (Romans 5:10). Our blessing (Gr. eulogein, lit. to speak well) may be verbal or tangible. Peter’s reference to inheriting a blessing reminds us of the inheritance he spoke of earlier and urged us to keep in view (1 Peter 1:4). However, God will give us this part of our inheritance only if we faithfully do His will (cf. Hebrews 12:17).
