You will know them by their fruit (see Matthew 7:20).
The fruit of knowing God, our Father, are righteousness, justice, wisdom, and holiness, which show through us as excellent character.
The fruit of knowing Jesus are compassion, forgiveness, knowing truth, healing, deliverance, liberty, and freedom, which manifest in us as compassion for and ministry to other people.
The fruit of the Spirit are love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. They show both in us and through us to others. Inside us, they are revealed through good character and, outside us, through compassion and ministry to others.
What’s in our heart will come out—Bad fruit or Good fruit!!
