There can be no doubt we live in uncertain times. On an international stage we are uncertain about future European relationships, threats from terrorism and climate change.
On a national stage we are uncertain we have provided safe housing for many who live in high-rise blocks with modern exterior cladding.
The local issues with which BBC Radio Bristol regularly deal include, today, uncertainty about care for sick children, provision of accident and emergency care in hospitals and the protection of an ancient tree.
Yet certainty is often less available than we think. I took for granted that this studio chair would take my weight. That the journey in would last the regular length. Emma trusts her alarm clock day by day (although her Twitter followers know how she feels about getting up). But there is no certainty.
We all live a little bit by faith, hope, trust. Without it we would disappear into a black hole of checking and double-checking. Checking everything all the time. Never trusting anyone or anything.
The Christian story is of a man who put his trust in God to such an extent that he died refusing to believe that this was anything other than God's will. Abandoned to die on a cross. Yet somehow still part of the plan.
Those of us who follow that man, Jesus Christ, must determine to do all we can to bring hope in uncertain times, to be servant as well as supervisor, good news when news is bad and light in the darkness. And that is the Gospel my friends.
