If I take the wings of the morningDavid has made this teaching about the Omnipresence of God very personal. He has spoken about himself in each of these verses, but in these two verses he move in just a little bit closer to the mind and heart of God. He reveals that God's presence isn't that of a bystander. God is where David is, and He is there with arms extended. He is helping David, He is leading him and guiding him. God is holding him up.
and dwell in the uttermost parts of the sea,
even there your hand shall lead me,
and your right hand shall hold me.
God's Omnipresence isn't that of a whispy vapor. He also isn't just "in" everything. He is PRESENT!
