This psalm has an abundance of the word "my." "My" is a wonderful intimate word. It implies ownership and connectedness, which is important because we live in a world that very often tells us that we do not have and that we do not belong.
And yet, for all the intimacy of the word "my" there is a connection to the larger picture. God created the great things in the universe, yet He is loving enough that he cares about the small issues in human life.
St Paul says we should cast all our care on God because God cares for us. Not just our large cares, or our important cares, or cares the world deems valid, or family cares, or world cares. God cares about the tiniest things and he can be as glorified in helping us find the perfect peanut butter if that's what our kids need to survive...as he can in healing a toothache or a cancer.
This psalm makes us aware that God is aware of me, myself, my and I.
As Hagar stated in the book of Genesis: "Thou, God, seest me."
1I cried unto the LORD with my voice; with my voice unto the LORD did I make my supplication.
2I poured out my complaint before him; I shewed before him my trouble.
3When my spirit was overwhelmed within me, then thou knewest my path. In the way wherein I walked have they privily laid a snare for me.
4I looked on my right hand, and beheld, but there was no man that would know me: refuge failed me; no man cared for my soul.
5I cried unto thee, O LORD: I said, Thou art my refuge and my portion in the land of the living.
6Attend unto my cry; for I am brought very low: deliver me from my persecutors; for they are stronger than I.
7Bring my soul out of prison, that I may praise thy name: the righteous shall compass me about; for thou shalt deal bountifully with me.
