He gives us the strength to say “no” to sin, and so, “yes” to God — say “yes” to God — and to say “yes” to obedience. And only God can do that. The Holy Spirit is God, and he does those mighty works in our lives and in our world. He rules over every event. He saves us, literally. He brings salvation that Jesus Christ earned into our lives and makes it ours. And He continues to change us until we meet Jesus someday.
Even though Christians insist that the Holy Spirit is fully divine, and that his works and personhood benefit us in many ways, we often don’t praise Him for these things in our worship, or even petition Him in our prayers.
