The question below is perfectly applicable to the topic and to the very question you just now posed.
Since Christ confirms that they are Believers in Him, Born-Again thru the Spirit of God,
what is the 'crown of Life' that He is promising them, since they already have Eternal Life in Him?
Do not be afraid. Jesus loves you and His answer supplies to us confidence in the Scripture.
Since you acknowledge the first resurrection is the resurrection of Christ man must have part in while living to be saved, and overcome the second death, it is clear the first resurrection is not physical. Yet you also insist the first resurrection is physical??? That's contradiction! Until you can acknowledge the first resurrection is spiritual, it seems we are at an impasse. And I believe you may be forecasting your fear of truth onto me. I have great assurance and confidence that I have correct doctrine, because my doctrinal position does not force contradiction into the Word of God. Sadly we cannot say the same for the doctrine you espouse regarding the "first resurrection".
