In this sermon Obedience, the Best Medicine, Man has always been required to believe and obey God. God warned Adam that he would die if he disobeyed by eating from the forbidden tree. This command gave Adam a choice. He could believe and obey, or not believe and disobey. As long as he believed and obeyed, he continued in fellowship with God and had eternal life. The consequence for disobeying God remains the same since the days of Adam—spiritual death, breaking fellowship with God, and missing His promises.
