The Garden of Eden was a perfect place: no striving, no strains, no struggles. But then Adam and Eve failed the volitional test as they partook from the Tree of the Knowledge of Good and Evil. They were driven from Eden, and work was now the order. Tilling the ground to make a living came with toil and sweat. Thorns and thistles made Adam's labor more difficult, and he ate his bread in sorrow.
While we cannot journey back to Eden in the physical sense, we can abide there mentally and emotionally. Thanks to the sacrifice of Jesus Christ, we can let our thoughts and words be governed by the Holy Spirit. And when we receive doctrine daily-as Adam and Eve did in Eden-our lives will be operating in the Truth.
Living inside the Garden represents personal daily fellowship with God. Many people are saved and know how to say spiritual things; they know how they ought to live. But they are living outside of the Garden, and their eternal purpose is limited.
Staying in the Garden brings lasting friendships that do not decay, spiritually. There you can live in a world filled with sin, yet you will not deteriorate morally.
The key is to stay inside the Garden.
