Psalm 139 is a great psalm that expressively describes God's knowledge of and commitment to us. Verse 14a - "I praise you for I am fearfully and wonderfully made (NRSV). It reminds us that we are part of God's big picture. Carla Grosch-Miller puts it like this in her version of Psalm 139 (in "Psalms Redux") - "We are a wonder, a miracle in flesh and blood: bodies that bruise and heal, minds that grasp and grow, hands that care, craft and create."
It is an amazing expression of God's concern with us - and we ought to take it seriously. As Michael Jagessar says, when commenting on this psalm (in "Fresh from the Word 2015"), "The psalm proclaims a relationship with God that is profoundly personal (not private). God knows me, cares about me, seeks me out."
How do we respond when God finds us and calls us to a particular task? As Michael Jagessar asks of us: "How does the knowledge of the all-attentive God who loves each of us intensely, shape your relationship and response to what you may be currently wrestling with?"
