The start of that title is an interesting bit in Matthew 28:17. It is made all the more interesting because of the liturgical day of Trinity Sunday.

What this sermon does is examine the current fetish with doubt, point to the real trouble which is not doubt itself but fear, and look at the ways that both fear and doubt are calls to The Faith, expressed in clear form like the creeds, and to faithfulness. Lastly, it attempts to knock down one of the great fears behind clear statements of the faith, by recalling Jesus’ final words and Peter’s Pentecost sermon…Let all Israel know for certain…(read/listen to the sermon to hear the rest).
