Consider the connection between “the tree of life” and “the tree of the knowledge of good and evil.” This relation is already suggested through the fact that they are both located “in the midst of the Garden” (Genesis 2:9).
But there is more between the two trees than just a geographical relation. It is because humans have taken the fruit of the tree of the knowledge of good and evil, because they disobeyed God, that they lost access to the tree of life, and could not live forever, at least in this condition. This connection underlies a profound principle. Moral and spiritual choices have an impact on biological life, as Solomon instructed to his son: “do not forget my law, but let your heart keep my commands; for length of days and long life and peace they will add to you” (Proverbs 3:1-2, , NKJV). This connection reappears in the future heavenly Jerusalem, where only the tree of life is present “in the middle of its street” (Revelation 22:2, NKJV).
“When God created Eve, He designed that she should possess neither inferiority nor superiority to the man, but that in all things she should be his equal. The holy pair were to have no interest independent of each other; and yet each had an individuality in thinking and acting. But after Eve’s sin, as she was first in the transgression, the Lord told her that Adam should rule over her. She was to be in subjection to her husband, and this was a part of the curse. In many cases the curse has made the lot of woman very grievous and her life a burden. The superiority which God has given man he has abused in many respects by exercising arbitrary power. Infinite wisdom devised the plan of redemption, which places the race on a second probation by giving them another trial.” — Ellen G. White, Testimonies for the Church, vol. 3, p. 484.
