Testing

I doubt that Jesus thought that his time in the desert would be easy. After all it is the place of testing. It is the point between where you were and where you know God wants you to be. Generally you don't know how large your desert is, your desert journey could last years, for others may only last days. But no matter what the desert is a hard place to be. Physically a desert is dry and hot, so the spiritual parallel would be an uncomfortable place. Maybe it is being in limbo, with no job or income. Or maybe it is just walking out of what you know, a situation that you know is not where God has called you to be but it is comfortable because your immediate needs are being met. But you take courage and walk out of that and into the unknown in obedience to Gods calling. One thing is for sure, when in the desert your destination looks way to far to be reachable and the land from which you came does not look all that bad anymore and is probably quite livable.

Jesus proved through his time of testing in the desert that even though He was God in the flesh, that he was still God over his flesh.

I am sure that even though His desert of testing He had to face before He started His ministry was hard, it was nothing compared to the last desert that He would face which was the desert between the last supper and the cross. This was the ultimate desert that no human could ever face. Every time He fell and got back up, he reaffirmed that He was God over His flesh. And as He died He took the sin of the world upon himself and sunk to the depths of hell and broke the chains of sin and death forever His desert was finally over, and He reached His destination at the right hand of God the Father.
Even though I was not there I imagine there was a victory parade in heaven as Jesus came back and I am sure the words "Well done, good and faithful Son" were heard.
