Last Sunday we baptized an infant. This Sunday we'll baptize an adult.
We usually don't have to explain to people why we baptize adults. We do have to explain why we baptize the children of believers. Recently the elders decided that we wouldn't do a "full-fledged explanation" every time we baptized a child, we'd just celebrate God's goodness.
But, we still do try to help those who don't "see" this in Scripture understand where we get it from. thus this link...
