Ephesians 4:31-32 says, “Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you with all malice. And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you.”
Romans 12:16 says, “Be of the same mind toward one another. Do not set your mind on high things, but associate with the humble. Do not be wise in your own opinion.”
In Colossians 3:12 Paul said to, “…put on tender mercies, kindness, humility, meekness, longsuffering.” Each of these attributes express the character of Jesus. Strong’s defines kindness as goodness in action, sweetness of disposition, and gentleness in dwelling with others. Kindness is a fruit of the Spirit. Galatians 5:22.
Note in my Bible: The word describes the ability to act for the welfare of those taxing your patience. The Holy Spirit removes abrasive qualities from the character of one under His control.
