"Therefore we are not discouraged. On the contrary, while our outer being wastes away, the inner self is renewed from day to day. The slight affliction that quickly passes away prepares us for an eternal wealth of glory so great and beyond all comparison. So we no longer pay attention to the things that are seen, but to those that are unseen, for the things that we see last for a moment, but that which cannot be seen is eternal.
We know that when our earthly dwelling, or rather our tent, is destroyed, we may count on a building from God, a heavenly dwelling not built by human hands, that lasts forever. Therefore we long and groan: Why may we not put on this heavenly dwelling over that which we have? (indeed, are we sure that we shall still be wearing our earthly dwelling and not be unclothed?) As long as we are in the fieldtent, we indeed moan our unbearable fate for we do not want this clothing to be removed from us; we would rather put the other over it, that the mortal body may be absorbed by true life. This is God's purpose for us, and he has given us the Spirit as a pledge of what we are to receive." (2 Corinthians 4:16-5:5)
