God provided a way of salvation not through offering complex religious ceremonies to be observed or moral requirements to be fulfilled. Instead, God provided a way of salvation by offering Himself. The Old Testament includes detailed instructions regarding religious ceremonies, sacrifices, and moral laws. However, these instructions were never intended to save, but to foreshadow and identify the One who would come to offer Himself as our salvation.
John 1:1-14, Hebrews
Jesus Christ is this One–the Jewish Messiah who came in fulfillment of the Old Testament promises. He is the One in whom all of the covenants, prophecies, sacrifices, and commandments find their conclusion by serving as the ultimate High Priest, eternal King, and divine Prophet. He is God who became a Middle Eastern man and lived during the reign of the Roman Empire. Although fully God, He lived as a human being experiencing all of the same temptations, emotions, difficulties, and joys we do. Although fully human, He never sinned in any way, but perfectly obeyed the commandments and requirements of the Scriptures.
Matthew 5:17-20, Philippians 2:5-11, Hebrews 4:14-16
Jesus Christ was an innocent man sentenced to Roman crucifixion. He willingly submitted to this sentence in accordance with the plan of salvation initiated by God from before creation. On the cross, Jesus Christ took our place by becoming a sinner before God. He received all of the judgment we deserve for our sins. Having exhausted the full wrath of God, He died and was buried in a tomb. Three days later, He physically rose from the dead and appeared to multiple witnesses. Afterwards, He ascended to heaven to reign over all things.
