The Resurrection of Christ was a hot topic in New Testament times. It was one of the most often preached topics of Peter and Paul. In fact, in Acts 23 when Paul "perceived that the one part were Sadducees, and the other Pharisees, he cried out in the council, Men and brethren, I am a Pharisee, the son of a Pharisee: of the hope and resurrection of the dead I am called in question." That sparked a division "For the Sadducees say that there is no resurrection, neither angel: but the Pharisees confess both." Paul told Timothy in 2 Tim.2:18 that Hymenaeus and Philetus had, "erred, saying that the resurrection is past already;…" False doctrine concerning the resurrection is not new. 1 Cor. 15 is mostly concerned with the resurrection and tells us "If the dead rise not, then is not Christ raised: And if Christ be not raised, your faith is vain; ye are yet in your sins." Verse 20-22 state, "But now is Christ risen from the dead, and become the first fruits of them that slept. For since by man came death, by man came also the resurrection of the dead. For as in Adam all die, even so in Christ shall all be made alive." Whether you are saved or not, you will be resurrected. Jesus spoke of this in John 5:28-29. "Marvel not at this: for the hour is coming in the which all that are in the graves shall hear His voice, And shall come forth: they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation." Verse 24 explains that salvation is not merited by those who do good. It is received by faith. Verse 29 is a result of faith in Christ, the New Birth. If you look at Rom. 10:9-13, we have an invitation to the lost to call upon the name of Christ. If you look at verse 9 you will see the importance of believing in the resurrection of Christ: "That if thou shalt confess with they mouth the Lord Jesus, and shalt believe in thine heart that God hath raised Him from the dead, thou shalt be saved." Remember 1 Cor.15:17, "And if Christ be not raised, your faith is vain…"
1 Peter 1:3, "Blessed be the God and Father of our Lord Jesus Christ, which according to His abundant mercy hath begotton us again unto a lively hope by the resurrection of Jesus Christ from the dead."
Revelation 1:18 Jesus states, "I am He that liveth, and was dead; and , behold, I am alive for evermore, Amen; and have the keys of hell and of death."
