SERMON AUDIO

It’s one thing to have other people think badly of you – but how much worse if you spend your life thinking badly of yourself! This is where the great news of the sacrifice and high priesthood of Jesus come into sharpest focus – there really is relief for our guilt, and the conscience pricks that come with it.

Join us in continuing our Hebrews series! This week, we’ll take a look at Hebrews 8-9 through a sermon titled “How to Clean a Conscience”.
