I wanted people to get themselves feeling in the position of Paul - through the sermon - and then to have an 'Ananias experience' at the end with O and I laying hands on them, the scales falling from their eyes, the Holy Spirit descending etc etc. (I think if I'd explained all this in advance O would have been truly alarmed!)
Nonetheless the lesson of all this is better communication. I really should have discussed it with O in detail before.
As it was, there was a lot of positive feedback on the sermon. Two people stood but many more said they had been really challenged afterwards. And three others signed up for next Alpha course.
So quite a success really. thank God.
