6 And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
One of the amazing things about how the Bible is written is in how God reveals things to us which are already performed by Him but not realized by us until their time has come. For instance, Jesus came to destroy the Devil who has power over physical, biological death.
Hebrews 2:14 Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; 15 And deliver them who through fear of death were all their lifetime subject to bondage.
The Devil, also known as Lucifer and Satan, still, at this present time, has power over death. Jesus came to die but in defiance of Satan’s power over death He rose again, belief upon which is the principal reason that God saves you from an eternity of agony, the soul of man’s natural fate with Satan. Death is the most consistent facet of our world, happening countless times every moment. It is Satan’s bailiwick. But, based on Christ’s intent we are waiting for the redemption of our physical body, the adoption.
Romans 8:23 And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
We who are trusting in Christ await the translation of the church, popularly called The Rapture.
1 Corinthians 15:51 ¶ Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, 52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
We are told to preach this doctrine to each other.
1 Thessalonians 4:13 ¶ But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope. 14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 15 For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. 16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words.
However, our appearances, the angels of our presence (Isaiah 63:9), are already in heaven with Christ. Just as Christ was able to be in two places at one time, so He has made us able to do the same.
John 3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
Take comfort, those who have trusted in Christ, that you are already seated with Him in heaven, and in your finite condition here are just waiting for that fact to be manifested upon our physical death or at the translation/rapture.
2 Corinthians 5:6 Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord: 7 (For we walk by faith, not by sight:) 8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.
