The second to last verse of Psalm 119 brings to fruition the center of the entire psalm:
Let me live that I may praise you,
and may your laws sustain me (175).
First, he wants to live so he can praise God or he wants to be delivered so he can praise God when he is delivered.
Second, it is his Torah that gives the psalmist the desire to live so he can praise God or he prays that God’s Torah will sustain him as he awaits God’s deliverance.
Either way we have the same: the psalmist wants to live a life that is shaped by praising God that emerges from dwelling in God’s Torah and living out that Torah. A life of praise; a life of learning and living Torah. That’s the entirety of this psalm.
