There must have been times when Jesus became frustrated and even exasperated with His disciples. It seems from the text of Mark 8:11-21, that this could have been one of those times.

Jesus stepped ashore where the Pharisees had gathered for one more chance to tempt him with their questions. When they asked for a sign, Jesus "sighed deeply in His Spirit" (v. 12). He had heard this request before. How could anyone reach these hardhearted men! Even if He did perform another sign, would they believe?

Back in the boat, the disciples discussed their only loaf of bread. This was not enough to feed everyone. Didn't they remember when He had fed the thousands? They had seen Jesus perform many miracles. Why couldn't they fit the pieces together? Why did they need another sign?

Jesus is the life changer.

The ultimate verification of our religion consists of the changed lives to which it can point and for which it is responsible.
