By him therefore let us offer the sacrifice of praise to God by continually, that is, the fruit of our lips giving thanks to his name (Hebrews 13:15)
The sacrifices of praise are the confessions, declarations, psalms, hymns, and spiritual songs of glory, grace and goodness of God that we make unto Him. It’s different from saying, “I praise you Lord, I just thank you for everything”…praise is more than that. Praising God means giving thanks to His Name for definite reasons.
In the Old Testament, the priests offered specific offerings to God; they offered sacrifices of burnt offerings and burnt incense, according to the specifications of the law. We also in the New Testaments are admonished to offer sacrifices of praise to God and Hebrews 13:15 clearly describes the Content of the sacrifice we’ve been called to offer: “By him(Jesus Christ) there-Fore let us offer the sacrifice of praise to God continually, that is, the fruit of our Lips giving thanks to his name.’’
As you worship the Lord and adore Him, making confessions to His Name, you’re offering unto Him the sacrifice of praise. As you offer quality praise and Present your body to Him as a living sacrifice, you send forth incense unto Him, and His presence rubs-off on you and overshadows you.
The “sacrifice of praise” comes from a humble heart that has been purified by fire. It arises from a spirit that chose to honor God. Very well observed in your text.
