I bet Matthew, also known as Levi, was watching all this going on...He had to know about Jesus, probably had heard Him teaching because when Jesus came by and said "Come, follow me", there was no hesitation...he got up and went.
Matthew was a tax collector. Tax collectors were considered to be one of the worst kind of sinners. As they went about their jobs of collecting taxes they were probably not very nice, and even known to take more than what was required by law, so they could put a little in their pockets...taking advantage of the people...
They were probably as popular then as IRS agents are today...not very welcomed when coming to audit our tax returns..
So when Jesus wanted to have anything to do with these kinds of people..the holier-than-thou religious folks didn't like it.
As I go about my life, I wander how many times I have, for whatever reason, snubbed someone because they were considered sinners?...Do I treat all people equally?...or am I just nice to those who meet my "acceptable" standard?
