When God expelled man from the garden of Eden, he secured the tree of life. Since Adam and Even had just eaten from the tree of the knowledge of good and evil, there was a possibility that they would eventually eat from the tree of life. In order to prevent that from happening, God secured the tree of life.
In Genesis 3:24 the Bible says,“So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life” (KJV). God placed security around the tree of life because of the possible severe consequences that would have come to man if he ate from it. Due to what happened, Adam and Eve now needed some external control. This was really God’s act of loves to man.
Today, man still needs external controls, otherwise there would be more suffering. Sin has brought suffering in this world and with that loss of internal controls because of disobedience, man needs external controls. However, when someone is in Christ, his internal faculties become activated. Such a one easily obeys God. In short, he has an ear to hear.
Do you have an ear to hear?
