At the first Passover in Egypt, the blood of the lambs that protected the Israelites was pointing to Jesus Christ. It was foreshadowing what He would do on the cross, when Jesus himself would become the Passover lamb, the lamb that was slain for all of humanity. His blood was shed in our place.
Jesus had been waiting for this moment. He was always in full control of everything that was happening in His life and ministry. He knew exactly what would take place next. He knew time was short and that His departure was at hand, when He would depart from this world to return to the Father. But He had certain things He had to accomplish before He went to the cross, a certain chain of events that had to take place. And the night before, He knew He basically had 12 hours before He would be crucified.
What if you had only 12 hours to live? Would you make any changes in your life? Would you be prepared to meet God? The Bible says, "Prepare to meet your God" (Amos 4:12).
God told Hezekiah, "Set your house in order, for your shall die and not live" (Isaiah 38:1). Is your house in order? By that I mean, are you ready to meet the Lord? If He were to come back today and call His own to be with Him in Heaven, would you be ready to go? If you died, would you be sure that you would go to Heaven? If not, you ought to make some changes.
Jesus knew what was coming. He dreaded it. He even recoiled from it. But He was going to demonstrate His love in a tangible way. So for the sake of His love for us all, He pressed on.
