For He was teaching His disciples and telling them, “The Son of Man is to be delivered into the hands of men, and they will kill Him; and when He has been killed, He will rise three days later.” Mark 9:31
Most of the disciples, by this point, believed Jesus is the Christ (Messiah) However their understanding of what the Christ (Messiah) would have to accomplish to reestablish Gods Kingdom was wrong. Now that God sent the Messiah, the King of Kings, and Lord of Lords, the disciples believed Jesus would rule with a rod of iron, destroy all their enemies, and reestablish the nation of Israel
However what they didn’t understand was Jesus came to save the entire world and not just the Jewish people. They also missed the Messianic Prophecies where the Christ would have to become the Lamb to take the sins of the world
But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. Isaiah 53:5
Nobody wants to talk about their God as a “Suffering Servant”. But this is exactly what Jesus had to accomplish at the cross to save the entire world from their sins. When Jesus told his disciples that he would have to be killed and then rise three days later, he was fulfilling the Messianic prophecies of Isaiah, he was also becoming the atoning sacrifice for our sins
Jesus lowered himself in obedience to save us from our sins! Glory to the Lamb of God Amen!
