Jesus has commanded us to live a life of love. “A new commandment I give unto you, That you love one another as I have loved you, that ye also love one another. By this shall all men know that you are my disciples, if ye have love one to another.” (John 13:34-35)
Jesus set this example for us. “Greater love hath no man than this, that a man lay down his life for his friends.” (John 15:13)
While he did literally lay down his life, you only have to do it figuratively. You are laying down your life for your friends by overlooking their shortcomings, and forgiving them when they hurt you. You are “crucifying” your old fleshy nature that seeks to punish them.
Keeping the Love Commandment is pretty much all that God requires of you. “For this is the love of God, that we keep his commandments: and his commandments are not grievous.” (1 John 5:3)
