Tolerance
As believers, we are to love, help, and accept one another no matter how different they are. Some people are weird. Maybe we are too and don't know. Remember Jesus telling us not to show preference to the rich man visiting and ignore the poor man?
Romans 15:5,6 Now the God of patience and consolation grant you to be likeminded one toward another according to Christ Jesus: That ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ.
When we allow the Spirit of The Lord to operate in our lives, we produce a symphony of harmony that the world can't duplicate as we glorify God together. This kind of unity is accomplished by tolerance.
