Waterbrook Lead Pastor Jeff Denton asks three questions: (1) What is a Christian?, (2) Are you a Christian?, and (3) Is anyone able to tell you're a Christian?. This challenge of what the designation of "Christian" as it goes back to when it was first introduced in the book of Acts. This sermon comes from the New Testament book of Acts 11:20-26. Originally preached at Waterbrook Bible Fellowship on Sunday, December 26, 2021.
