But when that which is perfect is come, then that which is in part shall be done away.
What does this refer to? The writing of and assembly of a book, or the final redemption of creation when Christ returns?
When the saints are with Christ then perfection has come, for they are no longer part of the world, and the things they must do on earth as part of living for God are passed away, except love, for that will be the only thing that will keep going on forever.
1Co 13:8 Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
1Co 13:9 For we know in part, and we prophesy in part.
1Co 13:10 But when that which is perfect is come, then that which is in part shall be done away.
1Co 13:11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
1Co 13:12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
1Co 13:13 And now abideth faith, hope, charity, these three; but the greatest of these is charity.
Prophesies are only needed on earth, and healings are only needed on earth, and knowledge is only needed on earth, and tongues is only needed on earth, for they are not needed in heaven for they are only things for the saints while on earth to help them in their walk with God, and to help the saint to be better, but when they are with Christ they do not apply anymore.
Out of faith, hope, and charity, which is love in action, charity is the greatest, because faith, and hope, are only needed on this earth, and are not needed in heaven for the saints are there so they do not need faith, and hope, concerning the afterlife, but charity will go on forever.
We cannot have perfection on earth, for there is prophesies still to come, and knowledge to be had for we grow in Christ, and tongues to be spoke, and healings to be done, so it is not perfection, but in heaven all that is passed away and not needed so it is perfection because there is no more growing, no more learning, no more people hurting needing a healing, no more future to be told, for the saints are at their final destination being with Christ that will go on forever in that same circumstance, and the growing, and the learning, and the advancement as a saint in Christ, does not occur anymore.
Out of all we done on earth only charity, love in action, will go on forever, and the only thing that the saints will be active in out of all they did on earth is charity.
