Let GOD deal with His enemies, He doesn't need our help or advice.
WE need not be concerned about any "enemies" at all.
WE have only ONE enemy,.....
......"And you know what is restraining him now so that he may be revealed in his time" (2 Thessalonians 2:6).
....it is God's spirit inside of us that restrains the evil one and keeps us from harm, not our knowledge and caution.
The devil and his demons have no hold on a righteous man, they can only "tempt", but have no HOLD. WE are the ones who causes wars, hatred, corruption, etc., not satan. Satan is powerless in our lives if we WANT him to be. Satan is a punk if we have God's spirit in us (and we should regard him so).
Psalm 82:6
"I say, "You are gods, sons of the Most High, all of you".
2 Timothy 1:7
"for God did not give us a spirit of timidity but a spirit of power and love and self-control".
God teaches STRENGTH (and self control to control that strength) and courage, NOT "fear".
