This excerpt comes from Psalms for All Seasons, commenting on Psalm 139:
Psalm 139 is a psalm of testimony about the limitless capacity for God to know us (v. 1) and to be present throughout all creation (vv. 7-12).
It includes a poignant testimony about God’s mysterious and majestic role in human conception and birth (vv. 13-16). The psalm then features a dramatic change, asking for God’s vengeance on faithless people (v. 19) and guidance in the way of truth (v. 24).
The opening sections of the psalm are the most often used; the concluding section, however, makes it clear that the psalm is about the choice for righteousness (cf. Ps. 1) and expression of awareness not only of God’s pervasive knowledge about us but also readiness for God to examine and text us (vv. 23-24).
Prayer for reflection:
Almighty God, creator of all things, you know each of us so intimately
that no thought in our minds or cell in our bodies is hid from your eyes.
Secure in the loving embrace of our brother, Jesus Christ,
we open our hearts and lives to your searching gaze. Amen.
