I am not going to give an answer here!
But I think this question should be asked every time we prepare a sermon. Indeed, we should ask it every time we prepare a service.
The answer we give to the question may vary around a central core (see the way the four gospels are different yet similar, centred on Jesus) but it should guide our preparation in such a way that what we present through preaching and worship leading renews confidence in the gospel in each member of the congregation.
Have a fruitful Holy Week!
