"Bless your persecutors; never curse them, bless them. ... Never pay back evil with evil. ... Never try to get revenge. ... If your enemy is hungry, give him something to eat; if thirsty, something to drink. ... Do not be mastered by evil, but master evil with good" (Romans 12:14-21).
These words cut to the heart of the spiritual life. They make it clear what it means to choose life, not death, to choose blessings not curses. But what is asked of us here goes against the grain of our human nature. We will only be able to act according to Paul's words by knowing with our whole beings that what we are asked to do for others is what God has done for us.
For further reflection...
Let no-one say when he is tempted, "I am being tempted by God"; for God cannot be tempted by evil, and he himself cannot be tempted by anyone. - James 1: 13 (NIV)
