All of that sounds good, but it's mostly wishful thinking.Enemies are to be fought, just not in a carnal way, we fight the enemy and our enemies with the Word of God, we hate the sin not the sinner, for we all sin, and whoever says he doesn't the truth is not in him, God is God, and God is love, He hates that which is not of love, and that is sin, not what He created in His image.
We fight 3 enemies, and our fight is not only spiritual but it's also bloody. Our first and greatest enemy is ourself, the second is the Devil, and the third is the world.
God does command us to kill our enemies in wartime, so there's nothing wrong with killing people in a war. The same God commanded His chosen people to kill entire ethnic groups, including children and pregnant women. We have plenty of examples where God commands us to kill our enemies.
When it comes to the devil, we fight Him with the sword of the Word of God, likewise, we fight ourselves with the same spiritual sword.
God doesn't just hate the sin, but He hates the sinner so much that He torments him in flames for all eternity. This is the true God which most Christians hate.
