For love to last in any relationship then it must be established on the foundation of God’s Word and the knowledge of Him.
Love must have a foundation to stand strong against the storms that will assail against it. A loving relationship is like a house and it must be built upon the right foundation. The foundation must be immovable and unchangeable because people, relationships and circumstances change. If a marriage or friendship has the right foundation then it will grow stronger over time and become sweeter to those who abide in the relationship where love is strong.
As long as Adam kept the commandment of God then he would live and he would be able to experience love and give love. The moment that he would disobey God then he would die.
