They are all happenings that were remembered as people listed their ideas of why Jesus was important. They pointed to these three events-Jesus' birth, Jesus' baptism, the visit of the Magi and Jesus' first miracle. Those epiphanies are important to our life of faith. Epiphanies require change on our part. Sometimes change is something that we would prefer to leave behind, especially if we're comfortable in our lives.
Epiphanies are new revelations that challenge.
New things that we learn, and it's impossible for us to learn something new and not be changed. If we're not changed by something that happens to us, we haven't learned anything new. So we go through our lives, we have experiences and those experiences change us. I said that there was a tie-in between baptism and the children's sermon with the leaf and the winter song of Longfellow that we just sang together. That tie-in comes from Paul's words.
