Paul lists the fruit of the spirit in Galatians 5:22-26. He tells us that when we've put our faith in Jesus and been born again by the power of the Holy Spirit we have found victory in Jesus. As we walk in the Spirit, with victory in hand, our life should begin to look different: we should bear a different kind of fruit from before. Not by struggling and striving, but by the power of the Holy Spirit it gradually and certainly appears.
