Remember, there were three steps to Calvary The way to accept Calvary in our individual life is to accept the death,burial, and resurrection of Christ.
We don't have to literally die,literally be buried, and literally rise again. Jesus was our substitute and did this for us. All we must do is accept what he did by spiritually dying, symbolically being buried, and spiritually rising again.
We take on his death by repentance which is spiritual death. When a person truly repents, he dies out to his own will, renounces it forever, and vows to live from that time on according to the will of Jesus Christ.
We take on his burial by baptism in water, by immersion into His name.
Romans 6:4 says, "Therefore we are buried with him by baptism". Baptism MUST be done by immersion; for something cannot be buried by sprinkling a little dirt on the top of it. That burial after a few days would certainly prove to be insufficient! Furthermore, EVERY baptism of which we have Biblical record was administered by immersion. That alone should determine our course of action on this matter.
Finally, we partake of the resurrection of Jesus Christ by the infilling of the Holy Ghost. This is the new life that enables us to live as a Christian should.
We see then that being born again means to spiritually die, symbolically be buried. Thus, in plain language an individual must repent of his sins, be baptized into the name of Jesus Christ by immersion, and receive the gift of the Holy Ghost. IJohn 5:8 tells us, "And there are three that bear witness in the earth, the Spirit, and the water, and the blood: and these three agree in one." What is the one thing in which the spirit, water, and blood agree? Is it not the new birth? Blood covers our sins at repentance; the waters of baptism wash them away, thus making us clean for the spirit to come into our lives to dwell.
When the Roman soldiers thrust the spear into Jesus' side after he died, the scripture tells us that there came forth blood and water (John 19:34). This was for cleansing of the nations. It takes blood and water to eradicate sin. Blood is the cleansing agent, and water is the flushing agent. When a jar is washed for canning, soap AND water are necessary to cleanse that jar so that it might be filled with good fruit. Likewise, blood and water are necessary to cleanse the human soul so that it may receive the spirit of Christ which is the Holy Ghost. This teaching was verified by Peter when he said, "Repent and be baptized FOR the REMISSION of SINS" (Acts 2:38). Repentance and baptism are both absolutely essential for the remission of sins!
