Now I say this, brethren, that flesh and blood cannot inherit the kingdom of God; nor does the perishable inherit the imperishable. Behold, I tell you a mystery; we will not all sleep, 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. (1 Corinthians 15:50-52)
The resurrection of Jesus Christ some 2,000 years ago fulfilled a number of prophecies concerning His Messianic ministry. His resurrection also guaranteed that those who belong to Christ will also be resurrected with new bodies like His suited for eternity; But now Christ has been raised from the dead, the first fruits of those who are asleep. For since by a man came death, by a man also came the resurrection of the dead. For as in Adam all die, so also in Christ all will be made alive. But each in his own order; Christ the first fruits, after that those who are Christ's at His coming. (1 Corinthians 15:20-23)
Those who would deny the bodily resurrection of Jesus Christ are also rejecting the Bible's promise of our future bodily resurrection, as well as, the gospel of forgiveness of sins and eternal life; For if the dead are not raised, not even Christ has been raised; and if Christ has not been raised, your faith is worthless; you are still in your sins. Then those also who have fallen asleep in Christ have perished. (1 Corinthians 15:16-18)
But now Christ has been raised from the dead...! Our faith in Him and the promise of our coming resurrection with imperishable bodies is assured; Now faith is the assurance of things hoped for, the conviction of things not seen. (Hebrew 11:1) Maranatha!
