Like Adam, we can choose to eat from either tree, but we cannot eat from both. Adam sinned when he fell into the flesh and yielded to his Self-life. He rejected the Tree of Life in favor of something that was “good… pleasant… and desirable” (Genesis 3:6). The Cross does not look like a Tree of Life at all. It is neither good, nor pleasant, nor desirable. It looks like death. Perhaps this is why Adam did not eat from it first.
But God’s End is not death, regardless of appearances: God’s End is Life out of death, which is resurrection. To eat of the fruit of the Tree of Life is to glory in the Cross of Jesus Christ and find Life out of death. It is becoming popular to preach and teach about the Cross these days, but how many are eating of its fruit? Can we really see the Cross as the TREE OF LIFE, and are we eating its fruit? We will know a true disciple of the Lord, not by words, but by fruit, and the Cross is the Tree of Life from which this fruit comes.
