They will know we are Christians by our love, unity, community, generosity, joy, sincerity, and favor. It shows God’s presence, enabling, and kindness coming through in our lives, thanks to the fruits of the Spirit described in Acts 2:44-47 and Galatians 5:22-23. God’s kindness leads to repentance. People repent. They change their mind about Jesus and the church when we are thriving. New people will come to church and the church will grow!
