The baptism follows true repentance. Moroni admonishes us that it is important that it follow that repentance. We should take care that “ye are not baptized unworthily.” Similarly, we should “not partake of the sacrament of Christ unworthily.” These are ordinances that connect us with the powers of heaven, and they should only be performed by those who approach them worthily. The process of doing so is simple, and involves repentance. If we approach these ordinances truly repentant, then they will dead us to the reward with God. If we have not repented, they will do us no good, and we will be cast out. While the ordinance if recognized by God, it is nevertheless a witness to a change in our souls. Neither the baptism nor the renewal of that covenant in the sacrament makes a change in us. The repentant heart is confirmed through those ordinances, and the atonement is applied.
