Jesus was our sacrifice “Once” for our sins to bring us to God. He was put to death in the flesh but quickened by the Holy Spirit. (His body died like we all will do. Our new body awaits us.)
Jesus is IN US by the Holy Spirit and we are to do the works that He did. We remember his words in - - Luke 10:19 Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing will injure you.
Ephesians4:8,9 "Now that he (Christ) ascended, what is it but that he also descended first into the lower parts of the earth...Wherefore he saith, When he ascended up on high, he (Christ) lead captivity captive (those in Paradise to Heaven), and gave gifts unto men."
Matthew 27: 52-53 Many bodies of the saints who had fallen asleep were raised; and coming out of the graves after His resurrection, they went into the holy city and appeared to many.
Peter declares Noah’s ark and the water was a symbol of baptism and a testimony that we are dead to our old life, buried with Jesus and resurrected to live a new life IN HIM. We are saved by receiving Jesus into our life, and baptism is a testimony in obedience to that truth. Baptism does NOT save us, but if at all possible it is something we should do. We are reminded that the good thief on the cross did not have time to be baptized, yet Jesus declared that the thief would be saved that day.
1 Peter 1 20-21 In it only a few people, eight in all, were saved through water, and this water symbolizes baptism that now saves you also—not the removal of dirt from the body but the pledge of a clear conscience toward God. It saves you by the resurrection of Jesus Christ, who has gone into heaven and is at God’s right hand—with angels, authorities and powers in submission to him.
