The Holy Spirit is the Spirit of our Lord Jesus Messiah.  The fruit of the Spirit is the character of Christ.  “The fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control” Gal 5:22-23a.  This is the evidence that the Spirit is in us.  He is inside us as the shaping Potter.  He is in us as the River flowing through us.  He is in us as the Gardener cultivating fruitfulness.  He is in us as our Coach teaching us how to run the race.  He is in us as our Warrior teaching us how to overcome.  He is in us as the Servant teaching us how to be servants.  He is in us as the Crucified One, teaching us how to die.  He is in us as the Risen One teaching us how to come back when it looks like we have been taken down.
