1 Chronicles 16:4
He appointed some of the Levites to minister before the ark of the LORD, to make petition, to give thanks, and to praise the LORD, the God of Israel:
It is no surprise that some of the Levite priests were appointed to work in the presence of the ark of the Lord and they were expected to pray and give thanks there. But this work isn’t reserved for just a special class of Israelites. The Levites were the ones appointed to work in front of the ark but all are called to give thanks and praise the Lord.
God told Moses that Israel would be a “kingdom of priests” in Exodus 19:6. But this designation is extended to all Christians as well. Revelation 1:6 addresses all Christians as such. “To him who loves us and has freed us from our sins by his blood, and has made us to be a kingdom and priests to serve his God and Father…”
We are all ministers of thanks. One of our chief duties as Christians is to thank God for what He has provided. Of course one of the things that we have to thank God for is who He is. This is praise.
Praise and thanksgiving go hand in hand. Both are natural expressions of love for God. Thanksgiving can be general thanks for anything that God has done or has given us. Praise can be thought of as specific type of thanks where we thank God for all of who He is – all of the qualities that make God so praiseworthy.
