Genesis 3:22-24

22-24 God bid man go out; told him he should no longer occupy and enjoy that garden: but man liked the place, and was unwilling to leave it, therefore God made him go out. This signified the shutting out of him, and all his guilty race, from that communion with God, which was the bliss and glory of paradise. But man was only sent to till the ground out of which he was taken. He was sent to a place of toil, not to a place of torment. Our first parents were shut out from the privileges of their state of innocency, yet they were not left to despair. The way to the tree of life was shut. It was henceforward in vain for him and his to expect righteousness, life, and happiness, by the covenant of works; for the command of that covenant being broken, the curse of it is in full force: we are all undone, if we are judged by that covenant. God revealed this to Adam, not to drive him to despair, but to quicken him to look for life and happiness in the promised Seed, by whom a new and living way into the holiest is laid open for us.
