Continuing in our series on the Holy Spirit, this week we focus on what the Spirit does in terms of changing us. The New Testament tells us that the Holy Spirit not only gives gifts to Chrsitians, but also causes new behavior and transformation in them: what St. Paul describes in Galatians 5 as the fruit of the Spirit - love, joy, peace, patience, goodness, kindness, faithfulness, gentleness, and self control. Like a healthy plant or tree that bears good fruit, so the work of the Holy Spirit is to produce these things in us.
