Do I Cor 15:51-54 speak of the first resurrection (Rev 20:6) since I Peter 1:23 says we've "Been born again of incorruptible seed" (Rm 8:9) ?

"Being born again [John 3:5-8], not of corruptible seed, but of incorruptible" (I Peter 1:23) and I Cor 15:54 says "So when this corruptible shall have put on incorruption..."

Rm 8:9 says "But ye are not in the flesh but in the Spirit" and I Cor 15:54 says "...and this mortal shall have put on immortality" that is "not in the flesh" (Romans 8:9).

This (((IS)))

>>>>>>>"THE FIRST RESURRECTION"<<<<<< (Rev 20:6)

When resurrected from our DEAD spirits (Rm 5:12-14; I Cor 15:21-22)

THIS IS (((TOO DEEP))) FOR TODAY'S CHRISTIANS!

BUT 

"Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years" (Revelation 20:6).

"So also is the resurrection of the dead [spirits; Rm 5:12-14; I Cor 15:21-22]. 

It is sown in corruption; it is raised in incorruption [ I Peter 1:23]: 

It is sown in dishonour; it is raised in glory ["by the glory of the Father" Rm 6:4]: 

it is sown in weakness; it is raised in POWER [Received after Holy Spirit baptism; Acts 1:5;8]: 

It is sown a natural body; it is raised a spiritual body [Rm 8:9 not in the flesh]. There is a natural body, and there is a spiritual body" (I Cor 15:42-44)..

"Blessed and holy is he that hath part in (((THE FIRST RESURRECTION:))) on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years" (Revelation 20:6).

“But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:” (I Peter 2:9)!

(((TOO DEEP!))) 

"But God hath revealed them unto us by His Spirit: for the Spirit searcheth all things, yea, the (((DEEP))) things of God" (I Corinthians 2:10).
