Let this Messiah, this King of Israel, come down from the cross so we can see it and believe him!” Even the men who were crucified with Jesus ridiculed him.
Don't we do similar things?
We tell God we will believe in Him if He does certain things that we require.
So, in essence, we tell God that we will let Him be God if He serves us.
See how backwards that is?
In that scenario, we are god and judge.
But God refuses to bow to us.
He insists on dying for us, even when we're trying to insist that we want Him to do something else for us.
