Getting things done:
“Where there are no oxen, the manger is clean, but abundant crops come by the strength of the ox.” (Proverbs 14:4)
You need to do both. But things will not stay perfectly organized, and there will be times when they get almost totally out of hand.
That’s OK. The manger won’t always be clean, and it’s worth it.
Keep things as orderly as you can, and when they get out of control for a while, make sure to eventually take time to clear the decks.
You shouldn’t generally have to chose. But if you have to for a time, fruitfulness is more important than organization.
And, don’t begrudge the time you have to spend getting and keeping things organized. That’s a necessary part of things, which is the main point of the verse.
