LDS Baptism is not about what God does for them, but what they promise to do for God.
“When you were baptized, you entered into a covenant with God. You promised to take upon yourself the name of Jesus Christ, keep His commandments, and serve Him to the end. You renew this covenant each time you partake of the sacrament” (True to the Faith, p. 23).
They are baptized by immersion either at the age of eight or when they convert. Mormons consider a baptism valid only if it is performed by a holder of their priesthood. Even though they are baptized with water in the name of the Father, and of the Son, and of the Holy Ghost (D&C 20:73), it is not a valid Christian baptism since the LDS church is not a Christian church.
Biblical Christianity teaches that God wonderfully uses baptism to connect people to Christ (Romans 6:3-4). Through it, God bestows the benefits of Christ’s perfect life and sacrificial death. The blessings of baptism include the forgiveness of sins (Acts 2:38), a new spiritual life (Romans 6:4), and eternal salvation (1 Peter 3:21).
