As an aspect of God goodness, He expresses kindness towards us so that we feel at ease with who we are in Christ. We can show this kindness to others by expressing this aspect of the fruit of the Spirit. Also, remember, it is God’s kindness not wrath that brings us to repentance, a change of the mind. It is not about going to hell; it is about being saved. Through kindness we can show others an aspect of God’s character and perhaps bring some to also believe God.
