"For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ, who will transform our lowly body that it may be conformed to His glorious body, according to the working by which He is able even to subdue all things to Himself" (Philippians 3:20-21 Philippians 3:20-21  For our conversation is in heaven; from where also we look for the Savior, the Lord Jesus Christ:
 Who shall change our vile body, that it may be fashioned like to his glorious body, according to the working whereby he is able even to subdue all things to himself.

Be sure to read Paul's description in 1 Corinthians 15:50-54 1 Corinthians 15:50-54  Now this I say, brothers, that flesh and blood cannot inherit the kingdom of God; neither does corruption inherit incorruption.
 Behold, I show you a mystery; We shall not all sleep, but we shall all be changed,
 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.
 For this corruptible must put on incorruption, and this mortal must put on immortality.
 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
American King James Version×of our final transformation from our "lowly" physical, mortal bodies to glorious, immortal spirit bodies. The apostle Peter summarizes the transformation that God accomplishes in His saints in these words: "His divine power has given us everything needed for life and godliness, through the knowledge of him who called us by his own glory and goodness. Thus he has given us, through these things, his precious and very great promises, so that through them you may escape from the corruption that is in the world because of lust, and may become participants of the divine nature" (2 Peter 1:3-4 2 Peter 1:3-4  According as his divine power has given to us all things that pertain to life and godliness, through the knowledge of him that has called us to glory and virtue:  Whereby are given to us exceeding great and precious promises: that by these you might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
