Without the resurrection we are still in our sin! Why? Because of Jesus’ claimed before His Death that he would be raised. If He was gone without sure word of testimony it would be just a leap of Faith, But When He arose that gave us confidence in His Finished Work.

What does Paul teach us about our future as it relates to the resurrection of Jesus?
I Corinthians 15
20 But the fact is that Christ has been raised from the dead. He has become the first of a great harvest of those who will be raised to life again.
21 So you see, just as death came into the world through a man, Adam, now the resurrection from the dead has begun through another man, Christ.
22 Everyone dies because all of us are related to Adam, the first man. But all who are related to Christ, the other man, will be given new life.
23 But there is an order to this resurrection: Christ was raised first; then when Christ comes back, all his people will be raised.

Nothing That I can say tells it better that Paul in the following verses.
I Corinthians 15
43 Our bodies now disappoint us, but when they are raised, they will be full of glory. They are weak now, but when they are raised, they will be full of power.
44 They are natural human bodies now, but when they are raised, they will be spiritual bodies. For just as there are natural bodies, so also there are spiritual bodies.
45 The Scriptures tell us, "The first man, Adam, became a living person." But the last Adam--that is, Christ--is a life-giving Spirit.
46 What came first was the natural body, then the spiritual body comes later.
47 Adam, the first man, was made from the dust of the earth, while Christ, the second man, came from heaven.
48 Every human being has an earthly body just like Adam's, but our heavenly bodies will be just like Christ's.
49 Just as we are now like Adam, the man of the earth, so we will someday be like Christ, the man from heaven.
50 What I am saying, dear brothers and sisters, is that flesh and blood cannot inherit the Kingdom of God. These perishable bodies of ours are not able to live forever.
51 But let me tell you a wonderful secret God has revealed to us. Not all of us will die, but we will all be transformed.
52 It will happen in a moment, in the blinking of an eye, when the last trumpet is blown. For when the trumpet sounds, the Christians who have died will be raised with transformed bodies. And then we who are living will be transformed so that we will never die.
53 For our perishable earthly bodies must be transformed into heavenly bodies that will never die.
54 When this happens--when our perishable earthly bodies have been transformed into heavenly bodies that will never die--then at last the Scriptures will come true:"Death is swallowed up in victory
55 O death, where is your victory?O death, where is your sting?"
56 For sin is the sting that results in death, and the law gives sin its power.
57 How we thank God, who gives us victory over sin and death through Jesus Christ our Lord!

What great and precious promises that are given us from God! I would like to look once again at verse fourth-eight and fourty-nine, above.
48 Every human being has an earthly body just like Adam's, but our heavenly bodies will be just like Christ's.
49 Just as we are now like Adam, the man of the earth, so we will someday be like Christ, the man from heaven.
All Praise be unto God our Great Savior!
