“Therefore we are always confident and know that as long as we are at home in the body we are away from the Lord.” (II Corinthians 5:6)
We are called to live our lives, not by what is seen but by what is unseen (2 Cor. 4:18). Everything that can be seen, such as the things we own, will pass away. Even relationships or good intentions, if they are not grounded in eternity and the unseen, will be lost and meaningless. But when we live our lives for eternity, for the things that cannot now be seen in the physical, will last. They will be seen in the spirit, for only the spirit can see the things of the spirit. Relationships, gifts, love—all these, if grounded in the eternal and unseen, will not be in vain.
“Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your body.” (I Corinthians 6:19-20)
God works through vessels. No longer would His presence among His people be temporary, but would rather be eternally within them. His kingdom would be a kingdom of hearts devoted to Him. Our spirit man longs to walk with God, talk with Him, commune with Him, and that can only be done in a pure temple, a pure vessel. God has called us to live by the Spirit so that His presence can be with us and go with us no matter what may come against us.
