The central teaching of the Lutheran Church is the teaching that sinful man is saved by God’s grace alone through faith. However, this faith does not originate within yourself; it is a gift from God. In order to deliver this faith the Holy Spirit uses instruments—or means—to deliver His grace.
The first of these means is Holy Baptism. Baptism is not just plain water, but it is water that is combined with and included with God’s Word. There is a promise attached to Holy Baptism. He who believes and is baptized will be saved, but he who does not believe will be damned (Mark 16:16). Holy Baptism is the washing of the Holy Spirit and of new birth (Titus 3:4-7). Baptism is salvation (1 Peter 3:21). Our churches teach that children are to be baptized. This promise of baptism is for us and for our children (Acts 2:38-39).
Holy Baptism is a precious gift by which God makes His enemies His children. By this water and promise He converts the rebellious, saves the sinner, and delivers from death to life.
