The Holy Spirit’s role in human life is to cause us to do good works. Whether that good work is confessing Jesus Christ as the Son of the living God or serving our neighbor, none of it happens apart from His intervention in our lives. Apart from Him, we are hopeless and dead. Consider how Dr. Luther taught it in his Small Catechism but put everything in the negative. Without the Holy Spirit we do not have the Gospel, we sit in darkness and in the shadow of death, we have no good gifts, and we have no right belief in Jesus Christ who has won our salvation. Without the Holy Spirit, life is lacking all those things that make it good. Without the Holy Spirit, everything is hopeless. But because we have the Holy Spirit, we are able to rejoice, to have hope in the midst of this world’s sadness, and have comfort in what lies ahead, all because the Holy Spirit gives us Jesus.
The holy spirit is the Spirit of confession. As Christ Our Lord said, the Holy Spirit “will teach you all things and bring to your remembrance all that I have said to you.” He confesses Christ to us, and by the faith He creates in us, we are able to confess Christ to others. That’s the whole point of this Feast of Pentecost. At Christ’s Ascension He gave His Church the solemn task of making disciples, that is, Baptizing and teaching, administering the Lord’s Supper, and forgiving the sins of all who repent. So just ten days after Jesus ascended into heaven, He poured out the Holy Spirit on His chosen disciples. And the Holy Spirit caused the apostles to confess in amazing ways. At St. Luke recorded in Acts, the apostles preached in languages which they had not learned. They preached that Jesus Christ died to take away the sin of the world. They preached that He rose victorious from the grave, the Father accepting His atoning sacrifice. They preached that Christ was giving His forgiveness and eternal life through Baptism, the washing of rebirth. And because of their Holy Spirit-given confession of the faith about 3,000 people were saved that day.
