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 has been in vain and your faith has been 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 being, the resurrection of the dead has also come through a human being; for as all die in Adam, so all will be made alive in Christ. (1 Corinthians 15:12-22, NRSV)
so all will be made alive in Christ!
There is resurrection from the dead, because if there isn’t then Christ was not raised. How can we say there is no resurrection of the dead if that is the case then Christ was not raised and the promise is null and void and we do not have any hope.
But the promise is real and we will be raised as He was raised. We will be made alive in Christ!
