We Must Be Baptized for the Remission of Our Sins

When we place our faith in Jesus Christ, repent, and are baptized, our sins are forgiven through the Atonement of Jesus Christ.
​
From the scriptures we learn that John the Baptist “did baptize in the wilderness, and preach the baptism of repentance for the remission of sins” (Mark 1:4). The Apostle Peter taught, “Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins” (Acts 2:38). Following Paul’s conversion, Ananias said to him, “Arise, and be baptized, and wash away thy sins” (Acts 22:16).

“All those who humble themselves before God, and desire to be baptized … that … have truly repented of all their sins … shall be received by baptism into his church” (D&C 20:37).

The Lord said, “If thou wilt turn unto me, and … repent of all thy transgressions [sins], and be baptized, even in water, in the name of mine Only Begotten Son, … ye shall receive the gift of the Holy Ghost” (Moses 6:52). - By LDS.ORG
