Atonement is reconciliation to God. For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement. We are made one with Him through salvation. Repentance is death.
Baptism is burial.
The Holy Ghost is resurrection. Faith moves us to believe God and His Word. Faith initiates our acknowledgement that we are sinners and that Jesus Christ is our Savior. When we have faith, we believe and will repent. We, as Paul did, must die to this flesh through repentance.
