I'm sure you fancy yourself to be a skilled marksman, but God doesn't need your help...
Romans
12:17 Recompense to no man evil for evil. Provide things honest in the sight of all men.
12:18 If it be possible, as much as lieth in you, live peaceably with all men.
12:19 Dearly beloved, avenge not yourselves, but [rather] give place unto wrath: for it is written,
Vengeance [is] mine; I will repay, saith the Lord.
12:20 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.
12:21 Be not overcome of evil, but
overcome evil with good.
I guess shooting him up with bullets is not on the table, huh?
