There was a point that Jesus could not even go on physically.  He had been beaten severely and was tasked with carrying his cross up a hill to his execution.  But he could not do it.

So in his utter weakness a soldier found a random stranger in the crowd and ordered him to carry the cross for Jesus.  His name was Simon.

There are times when we cannot do anything more physically.  Even Jesus had his limits.

Praying for a Simon.
