God has given us plenty of direction for our thought processes (come, let us reason together) and has blessed us with free will ... and I refuse to accept that God would want me to acquiesce to a murderer, thereby eliminating any effectiveness I may have for HIM.
As a born again Christian ... I go through this mental gymnastic three or four times a year in my (I try to) daily reading and prayer with Him.
I'm comfortable with killing an enemy that refuses to hear truth
I didn’t say you don’t shoot your enemy who is attacking. The question was how should we pray.
