The Resurrection of the Dead
1 Corinthians 15:12-18
12 Now if Christ is proclaimed as raised from the dead, how can some of you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, then not even Christ has been raised. 14 And if Christ has not been raised, then our preaching is in vain and your faith is in vain. 15 We are even found to be misrepresenting God, because we testified about God that he raised Christ, whom he did not raise if it is true that the dead are not raised. 16 For if the dead are not raised, not even Christ has been raised. 17 And if Christ has not been raised, your faith is futile and you are still in your sins. 18 Then those also who have fallen asleep in Christ have perished.
Either way, 1 Corinthians 15, needs to be read as a whole.
Not saying your wrong, just we believe differently.
17 And if Christ be not risen again, your faith is vain, for you are yet in your sins.
18 Then they also, who have fallen asleep in Christ, have perished.
19 If in this life only we have hope in Christ, we are of all men most miserable.
20 But now Christ is risen from the dead, the first-fruits of them that sleep.
21 *For by a man came death, and by a man the resurrection of the dead.
