Mark: I will be preaching from Mark 11 How about AN ENTRANCE, A TEMPLE, AND A WITHERED TREE for a title. I shall attempt to deal with all three in 25 mins, so that the AGM can start on time...
Lyn: Shall I quote you on the 25 mins! 8>) Thanks for info.
Mark: Not a chance - those are preaching minutes - you know, like dog years.
Lyn: Oh no - we will end up looking like this... [cartoon]
