Baptism Is in Similitude of the Death, Burial, and Resurrection of Christ
Romans 6:4
4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
Elder David A. Bednar said:
“We begin the process of being born again through exercising faith in Christ, repenting of our sins, and being baptized by immersion for the remission of sins by one having priesthood authority.
“‘Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life’ (Romans 6:4).
“And after we come out of the waters of baptism, our souls need to be continuously immersed in and saturated with the truth and the light of the Savior’s gospel. Sporadic and shallow dipping in the doctrine of Christ and partial participation in His restored Church cannot produce the spiritual transformation that enables us to walk in a newness of life. Rather, fidelity to covenants, constancy of commitment, and offering our whole soul unto God are required if we are to receive the blessings of eternity.”
