On the television show M*A*S*H, Dr. Charles Emerson Winchester III made it clear what separated him from everybody else. "I'm a Winchester," he was heard to say more than once. For him, it was his family name that made him superior to everyone else. Other people carry other burdens. One woman received her education at Harvard and found a way to work Harvard into every conversation. Congregations fall victim to the same problem. Churches become satisfied with their pasts to the point that they do not make the changes necessary to live in the present with the same degree of faithfulness shown in prior years. It's one thing to be proud of certain things, but it is possible to lean too heavily on a good past and live too scantily in the precious present.
That's what John the Baptist was dealing with in this lesson. In scripture's continuing assault on the religious people of the day, John the Baptist was completely unimpressed with the very thing that the Jewish people had built their lives upon. They were the "children of Abraham." That was their birthright and, they felt, it would never be taken from them.
Then comes John the Baptist. He tells them that just because they are children of Abraham doesn't mean that the requirements have been eased or that they can slack off. We hate to hear John the Baptist say that because we know how it translates to our situation. We can hear him now. "Just because you are members of the church, just because you give your weekly offerings, just because your great-grandparents were in this church, just because you are an officer, just because you are the minister, doesn't mean it is time to relax and take it easy and give in to this temptation of thinking this matter of being Christian is under control." In other words, don't presume your past has taken care of your present.
