There has been great tribulation on the earth. Still also in the future unto the time of Jacob's trouble for three and a half tears, then------
IMHO this is the next appearing of Christ.
because the Lord himself, in a shout, in the voice of a chief-messenger, and in the trump of God, shall come down from heaven, and the dead in Christ shall rise first, 1 Thes 4:16
And this I say, brethren, that flesh and blood the reign of God is not able to inherit, nor doth the corruption inherit the incorruption; lo, I tell you a secret; we indeed shall not all sleep, and we all shall be changed; in a moment, in the twinkling of an eye, in the last trumpet, for it shall sound, and the dead shall be raised incorruptible, and we -- we shall be changed: for it behoveth this corruptible to put on incorruption, and this mortal to put on immortality; 1 Cor 15:50-53
then we who are living, who are remaining over, together with them shall be caught away in clouds to meet the Lord in air, and so always with the Lord we shall be; 1 Thes 4:17
And Jesus said to them, 'Verily I say to you, that ye who did follow me, in the regeneration, when the Son of Man may sit upon a throne of his glory, shall sit -- ye also -- upon twelve thrones, judging the twelve tribes of Israel; Matt 19:28
And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years. 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. Rev 20:4,6
and didst make us to our God kings and priests, and we shall reign upon the earth.' Rev 5:10
beloved, now, children of God are we, and it was not yet manifested what we shall be, and we have known that if he may be manifested, like him we shall be, because we shall see him as he is; 1 John 3:2
And just for the record I believe 1 John 3:2 is relative to 1 Cor 13:10-12 The next appearing, the manifestation of Christ in when, the perfect is come, also to them who are, in Christ.
