The Rev. Dr. Mark Hargreaves gets his chance to preach on John 14 on a Sunday instead of at a funeral. This lets us dive deeply into the concept of faith and doubt, what we can know, what we cannot know, and how to live with that: “We could say that there are some things that we know with our head, and some things that we know in our heart. Both can be true…we can train ourselves to develop a ‘heart knowledge’ of Jesus.”
