The earth is a planet. The world is the systems of people living on it.
The earth is waiting for something to happen in the spirit – for the revelation of the sons and daughters of God. The bar & bat mitzvah of the ages…
The Spirit himself bears witness with our own spirits that we are children of God; and if we are children, then we are also heirs, heirs of God and joint-heirs with the Messiah — provided we are suffering with him in order also to be glorified with him.
I don’t think the sufferings we are going through now are even worth comparing with the glory that will be revealed to us in the future. The creation waits eagerly for the sons of God to be revealed; for the creation was made subject to frustration — not willingly, but because of the one who subjected it. But it was given a reliable hope that it too would be set free from its bondage to decay and would enjoy the freedom accompanying the glory that God’s children will have. We know that until now, the whole creation has been groaning as with the pains of childbirth; and not only it, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we continue waiting eagerly to be made sons — that is, to have our whole bodies redeemed and set free. It was in this hope that we were saved. But if we see what we hope for, it isn’t hope — after all, who hopes for what he already sees? But if we continue hoping for something we don’t see, then we still wait eagerly for it, with perseverance.
Romans 8:16-25 Complete Jewish Bible
The earth is waiting for us to rise up and manifest His glory and His Kingdom. What are we waiting for?
