The New Testament exists because the final, complete, decisive, lasting act of divine salvation happened when Jesus, the Messiah, came into the world. He was the final Adam (Romans 5:12-21), and the final prophet like Moses (Acts 3:22; 7:37), and the final Israel (Matthew 4:1-11), and the final high priest (Hebrews 7:23-24), and the final Passover sacrifice (1 Corinthians 5:7), and the final manna from heaven (John 6:31-32), and the final suffering servant of Isaiah 53 (Mark 10:45), and the final Son of Man of Daniel 7 (Matthew 24:30). His blood was the blood of the promised final new covenant in Jeremiah 31:31 (Luke 22:20). He therefore was the final, decisive Yes and Amen to all God’s promises (2 Corinthians 1:20).
