Vengeance Is The Lord's But It May Take A While

Romans 12:17 Recompense to no man evil for evil. Provide things honest in the sight of all men.
18 If it be possible, as much as lieth in you, live peaceably with all men.
19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.
21 Be not overcome of evil, but overcome evil with good.
