New Defender's Study Bible Notes
15:51 a mystery. This “mystery,” not revealed in previous ages, assures us that Christ’s second coming will be initiated by simultaneous resurrection and glorification of the dead in Christ and glorification of the bodies of those still living at the time. Note that all will be raised! There is no basis for the so-called “partial rapture” theory. This same mystery had been unveiled previously to the Thessalonian believers (I Thessalonians 4:13-17), but his epistle to that church did not include the more detailed specifications for the spiritual body as described here. That body would be immortal (that is, no longer subject to death) and incorruptible (that is, no longer subject even to decay, pain, disease, or other physical effects of the curse). Paul would soon point out essentially this same truth to the churches at Philippi (Philippians 3:20-21) and Colosse (Colossians 3:4). In none of these is there any instruction to look first for the Antichrist, or the great tribulation, or for anything except Christ Himself!
