Ephesians 4:31 Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: 32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.

We are expected to walk in love towards one another as God's children. It is love to cover multitude of sin, there would be challenges, but we choose peace instead. Even as God's children, we'll face circumstances that may try to provoke us to anger and resentment towards a fellow brother or sister we choose love instead. 

A believer must know that love his is nature now and we don't operate by the law of karma. This is a kingdom govern by love, to stop overflowing of wickedness, we must walk in love always. No evil speaking, no malicious communication in any way. 

1Peter 4:8 (MSG) Most of all, love each other as if your life depended on it. Love makes up for practically anything. 

In Colossians 3:14, it says, "Above all, clothe yourselves with love, which binds us all together in perfect harmony". This implied that love is the binding cord of our Christian relationship and walks among brethren. So walk in love towards one another. Verse 13 says "Make allowance for each other’s faults, and forgive anyone who offends you. Remember, the Lord forgave you, so you must forgive others".
