Matthew Poole and continuators on Hebrews 13:15

15 By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips, giving thanks to his name.

Therefore, introducing this Duty, shews it not only to issue from the former Priviledge of having Christ our Altar and Sacrifice, therefore we should use him, and sacrifice by him; and it is inferred as anticipating an Objection of these Hebrews, That if the Tabernacle-Service ceased, then they should have no Sacrifice to offer unto God; yea, saith the Apostle, Let us offer; which is not Hand-work, but Heart-work, by a Spirit of Faith on this Altar, the Sacrifice of Praise, 1 Pet. 2.5. such as God requireth and accepts above all the Sacrifices of Beasts, &c. Psalm 50.23. Praise for the Grace-Priviledge and Honour of being Denizens of his City, and of being brought home to it by suffering, Col. 1.11, 12. And this always throughout our Life to the God that is the Author and Destributer of all these Blessings to us.

This Sacrifice of Praise the Spirit interprets to be the Fruit of our Lips, which the Prophet stileth, Calves of the Lips, in Hosea 14.2. By both these must Synechdochically be understood the Spirit and Heart guiding the whole Man in this matter, Rom. 12.1. confessing that all it is capable of rendring, is due from it to God, even all of Love, Praise, Thanksgiving Honour, for its Redemption through Jesus Christ, whether continually expressed either by Lip or Life, as Psalm 50.23. 1 Cor. 6.20. Ephes. 5.20. Phil. 4.6, 7. Col. 3.17. 1 Thess. 5.17, 18.
