7. It is a sin to do less than your best. It is wrong to do [merely] well.
“Whatever your hand finds to do, do it with your might”
(Ecclesiastes 9:10 ). But be careful. Sometimes the “best” is a B+
sermon and spending time with your child. In other words, “best” always
involves more decisions than the one you are making at the moment. That
one means many other things are being left undone. So “best” is always
the whole thing, not just the detail of the moment.

I like how John Piper says we must do our best, with all of life and
not just one part to the sacrifice of all the rest. So I’d start with
doing your best in your relationship and communion with Christ, and
then let him set the priorities and responsibilities for your life and
do your best taking all of them into account and the relationships
between different priorities and responsibilities. This is an
encouragement and a challenge to my soul.
