Sacrifice thank offerings to God,After all of this talk about how much God does not need these offerings, He still says to do them, He still says to keep your vows. You see, the problem wasn't with the sacrifices, it was with the heart. God may not need us to do these things, but He still wants us to.
fulfill your vows to the Most High,
I read a passage in Deuteronomy 8 the other day that was talking about the Children of Israel's wanderings. God told them that He was testing them during that time to see if they would keep His commandments. But this is not just for His sake. He already knows whether or not we will be obedient, that is why it also tells us that He let them go hungry so that they will understand that they need to live by God's Word.
Living in God's way is the best way to live. God knows this, that is why He is telling us to do these things. The trials come so that we might see how much we need to depend on Him.
