The LORD God took the man and placed him in the garden of Eden to work it and watch over it. (Genesis 2:15, HCSB)
If salvation through Jesus Christ is a restoration of what was lost in the Fall, then what implication does this verse have for eternity? It seems unlikely that we will sit around on clouds, wearing togas and strumming little harps. I think it means we will work, joyously serving our Creator.
