I have to write two sermons for Sunday - one for our Baptism service and one (on the same passages, cos I'm lazy) for a guest preach two hours later (on renewed commitment).  So far I've done all the good minister stuff of reading commentaries, thinking and (even!) praying and am getting nowhere fast.  I have some ideas, but nothing is cohering.  If all else fails I'll have to blag something around my paired ideas -

• ordinary and special
• human and divine
• individual and corporate
• completion and continuation

Nothing special about the water itself - but a special moment for those involved.

A human choice (discuss!) in response to a divine command/call/invitation

An individual moment in a corporate/communal life; a communal responsibility and commitment

The completion of a stage of a journey - and the start of the next bit

Nothing original or special about these ideas but hopefully they will turn into something soon - please!
