Who better than the Apostle Paul can describe the power of the resurrection:
Yet whatever gains I had, these I have come to regard as loss because of Christ. More than that, I regard everything as loss because of the surpassing value of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things, and I regard them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law but one that comes through faith in Christ, the righteousness from God based on faith. I want to know Christ and the power of his resurrection and the sharing of his sufferings by becoming like him in his death, if somehow I may attain the resurrection from the dead. (Philippians 3:7-11)
When Paul writes “If somehow I may attain” he is telling us about our resurrection in Christ. We must die to ourselves to be raised with Christ. Paul said that he died daily.
It did not take long for some people in the Church to deny the resurrection:
Now if Christ is proclaimed as raised from the dead, how can some of you say there is no resurrection of the dead? If there is no resurrection of the dead, then Christ has not been raised, and if Christ has not been raised, then our proclamation is in vain and your faith is in vain. We are even found to be misrepresenting God, because we testified of God that he raised Christ—whom he did not raise if it is true that the dead are not raised. For if the dead are not raised, then Christ has not been raised. If Christ has not been raised, your faith is futile, and you are still in your sins. Then those also who have died in Christ have perished. If for this life only we have hoped in Christ, we are of all people most to be pitied.
But in fact Christ has been raised from the dead, the first fruits of those who have died. For since death came through a human, the resurrection of the dead has also come through a human, for as all die in Adam, so all will be made alive in Christ. But each in its own order: Christ the first fruits, then at his coming those who belong to Christ. (1 Corinthians 15:12-22)
A second controversy was whether or not Jesus was raised bodily. That controversy is still being stirred up by some scholars and theologians in our day:
But someone will ask, “How are the dead raised? With what kind of body do they come?” Fool! What you sow does not come to life unless it dies. And as for what you sow, you do not sow the body that is to be but a bare seed, perhaps of wheat or of some other grain. But God gives it a body as he has chosen and to each kind of seed its own body. Not all flesh is alike, but there is one flesh for humans, another for animals, another for birds, and another for fish. There are both heavenly bodies and earthly bodies, but the glory of the heavenly is one thing, and that of the earthly is another. There is one glory of the sun and another glory of the moon and another glory of the stars; indeed, star differs from star in glory.
So it is with the resurrection of the dead. What is sown is perishable; what is raised is imperishable. It is sown in dishonor; it is raised in glory. It is sown in weakness; it is raised in power. It is sown a physical body; it is raised a spiritual body. If there is a physical body, there is also a spiritual body. Thus it is written, “The first man, Adam, became a living being”; the last Adam became a life-giving spirit. But it is not the spiritual that is first but the physical and then the spiritual. The first man was from the earth, made of dust; the second man is[f] from heaven. As one of dust, so are those who are of the dust, and as one of heaven, so are those who are of heaven. Just as we have borne the image of the one of dust, we will also bear the image of the one of heaven.
What I am saying, brothers and sisters, is this: flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. Look, I will tell you a mystery! We will not all die,[h] but we will all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we will be changed. For this perishable body must put on imperishability, and this mortal body must put on immortality. When this perishable body puts on imperishability and this mortal body puts on immortality, then the saying that is written will be fulfilled:
“Death has been swallowed up in victory.”
“Where, O death, is your victory?
Where, O death, is your sting?”The sting of death is sin, and the power of sin is the law. But thanks be to God, who gives us the victory through our Lord Jesus Christ. (1 Corinthians 15:36-56)
As long as we have received Jesus we can be assured:
Anyone who does not have the Spirit of Christ does not belong to him. But if Christ is in you, then the body is dead because of sin, but the Spirit is life because of righteousness. If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will give life to your mortal bodies also through his Spirit that dwells in you. (Romans 8:9-11)
