“Then they also which are fallen asleep in Christ are perished.”
King James Version (KJV)
15:18 They who sleep in Christ - Who have died for him, or believing in him. Are perished - Have lost their life and being together.
1Co 15:18 Then they also which are fallen asleep in Christ are perished. All the Christians who had died had fallen into eternal sleep. There is hope, in that case, only in this life; no hope of immortality.
