What happened to the good world God created? In this Sunday School lesson, Pastor James Brown Jr. examines Genesis 1–3 to show that evil is not a substance God created, but the corruption and absence of the good that ought to be present. At the root of the Fall, Adam and Eve ceased receiving the good from God and sought to possess it apart from Him. The lesson traces this disorder through unbelief, autonomy, ingratitude, disordered desire, abdication, blame, and the corruption of their distinct vocations as man and woman. It then turns to Jesus Christ, the Last Adam, who obeys where Adam disobeyed, assumes responsibility where Adam abdicated, gives Himself for His Bride, and brings justification, renewal, and life. Biblical repentance therefore means more than avoiding obvious evil: by grace, it recovers the missing good—faith, obedience, responsibility, sacrificial service, communion, and life under the rule and reign of Jesus Christ.
