Follow peace with all men, and holiness, without which no man shall see the Lord: Hebrews 12:14 KJV
God tells us to be holy for He is Holy. In other words we are to strive to be like Him.
And ye shall be holy unto me: for I the Lord am holy, and have severed you from other people, that ye should be mine. Leviticus 20:26 KJV
Jesus sacrifice of Himself, the “Lamb slain from before the foundation of the world,” provides the ability to live a pure and righteous life.
What God requires He supernaturally inspires.
He also wants us to be at peacemakers where ever possible with all mankind. After all, He sent Jesus, the Prince of Peace to the world.
If it be possible, as much as lieth in you, live peaceably with all men. Romans 12:18 KJV
