Psalm 50

"I don't need the bulls you sacrifice;
I don't need the blood of goats.
What I want instead is your true thanks to God;
I want you to fulfill your vows to the Most High.
Trust me in your times of trouble,
and I will rescue you,
and you will give me glory."
Psalm 50:13-15

It is so easy to fall into the trap of going through the motions. Of believing that anything we sacrifice -- bulls, goats (back then) or money, time (today) -- benefits God. What a great reminder that it is ALL God's. He absolutely does not need us to sacrifice even one little whit of anything. He gains nothing from any sacrifice we make -- nothing. When we sacrifice with a right heart, the sacrifice benefits us.
