I came across this in my reading of the Psalms today. It’s found in Psalm 19:14.
Let the words of my mouth and the meditation of my heart be acceptable in Your sight, O Lord, my rock and my Redeemer.
What an incredible idea to keep before myself daily.
In the Old Testament, the Israelites prayed often that their sacrifices would be acceptable to God. This Psalm uses similar language, and this verse uses a term that is often associated with God’s acceptace of properly offered, literal sacrifice. But here, David uses it, refering not to bulls and lambs, but to “lip and life” sacrifices.
This needs to be something I pray daily, and strive for daily. That my life, the things I do, and the things I say, are acceptable before God.
