Several months ago my wife and I took a few children from our church to the zoo. The youngest of the bunch (3 years old) kept asking the same question for every animal we looked at: "what does it do?" When we saw the bears, he asked, "what does a bear do?" When we looked at the reptiles, he had to know, "what does an iguana do?" We often ask the same question regarding baptism: what does baptism do? Does it change my relationship with God?
