Proverbs 16:7 NKJV
When a man's ways please the Lord, He makes even his enemies to be at peace with him.
This passage reveals that peace is affected by outside influences. The devil causes our enemies to be against us and to act in a way that is annoying, frustrating or harmful toward us. That means he influences them in a negative way toward us so that there is no peace between us and them. When we walk in love and forgiveness, that pleases the Lord. When we attack the demonic spirit behind the person instead of attacking the person, God is pleased. Then the Lord will influence our enemies in a way that will cause them to think in a peaceful manner towards us. If they refuse to accept His suggestions, he will arrange things where they will no longer be able to annoy, frustrate or harm us. The key to peace when it comes to our enemies is responding to them in a manner that pleases God.
