“When you offer blind animals in sacrifice, is that not evil? And when you offer those that are lame or sick, is that not evil? Present that to your governor; will he accept you or show you favor? says the Lord of hosts. And now entreat the favor of God, that he may be gracious to us. With such a gift from your hand, will he show favor to any of you? says the Lord of hosts” (Malachi 1:8-9, ESV).
What’s the problem with offering lame or sick animals as a sacrifice? After all, they’re killed and eaten anyway. Deuteronomy 15:21 declared that blemished animals can’t be used for sacrifice to God: “But if it has any blemish, if it is lame or blind or has any serious blemish whatever, you shall not sacrifice it to the Lord your God.”
Malachi’s ministry was to the repatriated Jews whose families had returned to Judea from Babylonian captivity. In Malachi’s time the people seemed to be indifferent to God. So much so, that they weren’t totally obedient to the law of God.
They offered sacrifices, sure. But they offered inappropriate and improper sacrifices. They offered sacrifices to God that wouldn’t even find favor with the governing authorities! So, why would they offer something to God that wouldn’t even be acceptable to men?
God’s people are not so much different today. We do the same thing. We hold out the best for ourselves and give God our leftovers.
