“Let the Christ, the King of Israel, come down now from the cross that we may see and believe.” Those who were crucified with him also reviled him. (Mark 15:32 ESV)
As Jesus hung upon the cross there were many people gathered to watch the horrible event unfold. Many of the onlookers were hostile, but not all of them. Some that had gathered were believers, and still others were not. Those that had yet to believe were frightening the cruelty of the crucifixion by heaping prideful mockery upon Christ.
We don’t know the numbers but many people who followed Jesus to Golgotha where he was crucified were there to lament and mourn for him. There also were those present who did not believe. But the one defining difference in the two groups was their ideas about who Jesus was. It was a difference of belief.
My position is that belief is a choice. You choose what you do or do not believe. The scribes and religious people regularly asked Jesus to perform signs, but when he did they didn’t meet their super religious criteria, or they somehow cut out their scandalous religious pyramid scheme. So those guys chose not to believe in Jesus despite all the miracles he had performed in front of their eyes.
They taunted him. Casting their doubts in the form of dangling skepticism and might-have-been-belief, but the simple truth is that they had chosen not to believe Jesus was the messiah. What do you believe?
