1 Corinthians 15:18

Then they also that are fallen asleep in Christ have perished.

'fallen asleep in Christ' -i.e. deceased Christians.

'have perished' -Since no true forgiveness of sins was actually obtained, all dead Christians, are lost Christians.

'Whatever doctrine constrained them to regard their beloved associates in the faith as lost, must needs appear to them as in itself highly questionable.' (Willis p. 544)

Point to Note:

Shallow thinking on the resurrection of Christ still exists today. Somehow people think that if they can disprove the resurrection of Christ, then no God exists and hence no accountability. God disagrees. If Christ wasn't raised from the dead, GOD STILL EXISTS, SIN STILL EXISTS, ACCOUNTABILITY STILL EXISTS. Disproving the resurrection of Christ, simply means that EVERYBODY IS LOST!
