That's not a boast, but after the posts about the Holy Spirit being present and evangelicalism & entertainment it makes me ask of myself "how am I going to do this?".
Is it enough to invite God to come at the start of the meeting, or does there need to be more knee-time? Is it better to prepare a song list well in advance (the 'well' being variable, depending on who you are) or to sit down at 6.30am on Sunday and get something, fresh from the Spirit?
There are plenty more questions one could ask - and I have - but there's also a point where you have to say "Lord, I've done what I can, but for this to actually mean anything then YOU have to turn up and make a difference". And while my head knows different, my heart says that without God being directly involved then I might as well stay in bed with my wife or go shopping/running/walking etc instead of going to the nice Christian club for a bit of karaoke.
OTOH I'm quite looking forward to our meeting this morning.
