He saved others; He cannot save Himself. He is the King of Israel; let Him now come down from the cross, and we will believe in Him. He trusts in God; let Him deliver now, if He takes pleasure in Him; for He said, “I am the Son of God.” –Matthew 27:42-43
This is utter, shameful mockery. They didn’t truly have any desire to believe in Him. They had seen or heard of Jesus’s teachings and mighty works. He had raised Lazarus from the dead, and still they did not believe.
At this point, the reader might feel the impulse to want the Savior to in fact come down from that cross and silence the fools. But He doesn’t. He continues to suffer—for which we should be thankful.
Because He stayed on the cross in obedience to the Father, the wrath of God that the sins of His people deserved was satisfied in Him. Because He stayed on the cross, anyone who believes in Him should not perish, but have eternal life.
Jesus did something more amazing than miraculously coming down from the cross. He laid down His life and saved His people.
Moreover, perhaps some of those who mocked Him would be silenced just a few days later. It would have been bewildering to see Jesus come down from that cross. Imagine their awe if they were some who saw Him alive again.
