Our opening scripture captures the most powerful words of Jesus as He hung on the cross. If you read from verse 19 you get a much richer context, "After this, Jesus, knowing that all things were now accomplished, that the Scripture might be fulfilled, said, 'I thirst!' Now a vessel full of sour wine was sitting there; and they filled a sponge with sour wine, put it on hyssop, and put it to His mouth. So when Jesus had received the sour wine, He said, 'It is finished!' And bowing His head, He gave up His spirit". The scripture lets us know that Jesus knew that all things were accomplished for the fulfilment of the prophetic word. The sour wine He tasted symbolized that He was suffering and tasting death for every man. "It is finished" signaled that Jesus fully accomplished all the demands of God's justice for the salvation of man. When He arose He presented His blood before the Father sealing the securing of eternal redemption for man (Hebrews 9:12). He shouted, "All hail" when He met the women (after rising from death) signifying the completion of the salvation transaction (Matthew 28:9). The death of Jesus is the full and adequate payment for the penalty of man sins. Therefore don't live your life as though He did not finish the works. Don't add to the works of Christ. That is why they are called the finished works of Christ. Don't trust human ability for personal qualification in God's sight. His death is our qualification in God's sight. And this is the message that you have to preach in your world. Help people know that Jesus already paid. They don't have to pay anything. They just have to believe in Him. Paul told the Corinthian church, "For I determined not to know anything among you, save Jesus Christ, and Him crucified" (1 Corinthians 2:2). He knew what Christ's redemptive work meant. It means everything. Don't boast in human abilities. Let your boast be in His redemption work as Paul also stated to the Galatians, "But as for me, I will never boast about anything except the cross of our Lord Jesus Christ. The world has been crucified to me through the cross, and I to the world" (Galatians 6:14).
