Paul had just had his world rocked – turned completely upside down. He had to take this incredible zeal he had as a Pharisee, relinquish it, and then work out something new. He was a new plant, no longer just a seed, but a viable growing organism that needed to draw on something. Interestingly Paul does not go to the disciples at this point – he sets out on his own. Essentially he was taking some time to get fertilized – to let God work on Him … and he probably didn’t even know why at that point.
