Hebrews 13:15

Through him then let us offer up a sacrifice of praise to God continually, that is, the fruit of lips which make confession to his name.

The sacrifice of praise is another kind of sacrifice, being differentiated from the sin offering, supplied by Jesus in his atonement; and this other type of offering is similar to the various thank offerings that were made under the Law, but with this difference: theirs were offered only on certain stated occasions and according to certain established rules; but ours is offered at all times, "continually," in words of praise and thanksgiving, with confessions of Christ's love, mercy, and blessing, plus all other forms of giving God the glory through oral testimony. It has been repeatedly revealed in Hebrews that a Christian's conversation, in the last analysis, is not merely a measure of his devotion but also a means of increasing both his own faith and that of others. (See under Hebrews 3:13.) Every hour of every day the child of God should seek occasions to speak humbly and lovingly of the wonderful blessings in Christian service, of the love and mercy of God, of God's goodness, and of the peace and joy in believing.
