Genesis chapter 2 shows that God gave a real rest to man. And He also gave man the Garden of Eden. God wanted to be with man having fellowship with them.
What we need to pay a close attention here is that in the center of the Garden of Eden there was the tree of life as well as the tree of the knowledge of good and evil. This means they were supposed to eat from the tree of the life by trusting in the Word of God. God’s order not to eat any fruits from the tree of the knowledge of good and evil was given in order to remind them of the spiritual reality that they must not challenge God’s authority. God once said, “But of the tree of the knowledge of good and evil you shall not eat, for in the day you eat of it, you shall surely die” (Genesis 2:17). For this reason, we can admit that the tree of the knowledge of good and evil was placed there by God for all the human races. From man’s perspective, that didn’t make much sense, but in God’s eyes the tree was more than appropriate. It was an essential tree in God’s master plan for Him to reveal His righteousness. However, in the eyes of man, we may have such question as this; “Why did God create the tree of the knowledge of good and evil? I think it would be better not to create it at all.” It was because God wanted us to acknowledge His authority.
