What does the imminent coming of Christ for the Church mean?
It means believers alive at that point will not die physically but will all be changed, receiving a resurrection body like Christ's. Paul wrote as though it could happen in his lifetime, so it may be tonight, tomorrow, or ten years away; no set prophetic program must be fulfilled first.
Les explains that this secret had never been alluded to, hinted at, or spoken before Paul unveiled it: toward the end of time a group of believers will not die physically, but all be changed. Their resurrected body is fashioned after Christ's resurrection body—much like our physical body yet different, a spiritual body without blood, flesh and bone but activated by the Spirit. Because Paul writes as though it could happen in his lifetime, those who adhere to this line of teaching call it the imminent coming of Christ for the Church. It may be tonight, tomorrow, or ten years from now, but believers are to look for it expectantly at any time, since no set prophetic program must be fulfilled for this event to take place.
