On the last Passover that Jesus celebrated with His disciples, He knew what would happen soon. His Spirit knew what was being planned for Him. So why did He go there? You know that if it were you or me, our fear of death would’ve kept us away from that place. Jesus was as much human as we are, but He was also God and He knew that if He didn’t go and fulfill the Father’s will mankind would have no part in His Kingdom when it’s time is fulfilled.
So, why did Jesus go to Jerusalem that night? Because of His love for mankind, not just for the Jewish people but for all of humanity. God did this because He knew that we could not have a relationship with Him unless our sin debt had been paid fully and only Jesus could do that. The blood of bulls and lambs and goats could only atone temporarily for our sins as it did in the Old Testament, but the New Testament in Jesus’ blood is a permanent atonement for our sins if we will believe in Him for our salvation. That is the only requirement that we have to fulfill for our salvation and it is our belief which comes to us through the faith which is given to us also by God. We cannot choose to come to Him on our own but when we feel our broken state and know that we need Him, then we can cry out to Him and He will heal us by the blood of Jesus.
You may wonder why I said in the paragraph above that He will heal you by the blood of Jesus. We are under a curse of sin and before Jesus comes into our heart we are dead spiritually. It is this spiritual death which Jesus heals us of and quickens us by His Spirit to do His will for the rest of our days. God loves you and has always loved you. The only requirement for your salvation that you can accomplish is to respond to the Spirit of God which breaks your heart to bring you to the point of repentance knowing that you need Jesus as your Savior.
God sent His Son to bring salvation to Judea but since they refused to believe that He was the Christ, the world gained a Savior. Believe in Him for your salvation because it is found in no other. Salvation is by the grace of God given to us through Jesus and by Him only.
