13:15 sacrifice of praise. We no longer sacrifice the blood of animals to cover our sins, for Christ has “offered one sacrifice for sins forever” (Hebrews 10:12). Instead, we offer praises, the “[fruit] of our lips” (Psalm 50:23; Hosea 14:2). These are not to be offered only once each week, in a so-called worship service, or praise service, but continually! “In every thing give thanks” (I Thessalonians 5:18).
