|Why We Need Covenants
Over the many years, God made several contacts with humans. He interacted, among others, with Noah, Abraham, the children of Israel and the New Testament believers. God offered people certain benefits for faithfully following His Word.
God interacted with Adam and Eve. He told Adam if he ate of the fruit of the tree of the knowledge of good and evil, he would die. Naturally, the converse of that would be, if Adam did not eat of the fruit, he would not die. God promised him and, by extension, his progeny, life.
