I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth.
This is a passage that strikes me as very interesting. Why is being lukewarm not acceptable? When we chose to follow Christ, he wants us to follow him with all our hearts. I think this also can be applied to all that we do. Why do anything with less than all our effort? Do your best at all you do and be happy with your best.
