Throughout the Old Testament, God gradually prepared His people for Christ. God eliminated some of the effects of His people’s sins, and the gratitude of the people to God drew them closer to Him. In other words, God drew good from evil. He loved the people of the Old Testament mercifully. However, God’s promise of mercy was completely fulfilled only in the God-man, Jesus Christ. In and through Jesus Christ, God’s merciful love drew good from the evil of original sin and its effects. Original sin and its most damaging effects—i.e., darkening of the mind, weakening of the will, lack of integration in the body—were overcome only in Christ.
In order to redeem us, God “emptied Himself, taking the form of a servant, being born in the likeness of men” (Phil 2:7). Through the redemption, Christ satisfied God’s love for man, the love that was left unreturned by Adam and Eve when they sinned. Thus, through Christ, the friendship between God and man, put to death by original sin, was revived. As God, Christ was capable of responding to the divine love. In His humanity, Christ made a human response to the divine love—i.e., He committed His entire self to God. In other words, He acted as a priest. A priest is one who commits his entire self to God. As a priest—an office He possessed in His human nature, Christ loved. Christ loved the Father and the Holy Spirit as all human beings should. In other words, Christ loved the Father and the Holy Spirit as Adam and Eve should have.
