Psalm 139 is a prayer that David prayed when he was in trouble and suffering unjustly. It is interesting what he said, which takes up most of the psalm, before he came to the short request. I will quote it to put it before our eyes. To me, it puts things into proper perspective and should set our hearts to singing with thanksgiving and trust as we prepare to seek His aid. He is always and only our sole help, though He may use people as a means of giving it.
Oh Lord, You have searched me and known me.
You know my sitting down and my rising up;
You understand my thought afar off, You comprehend my path and my lying down,
And are aquanted with all my ways.
For there is not a word on my tongue,
But behold, O Lord, You know it altogether.
You have hedged me behind and before,
And laid Your hand upon me.
Such knowledge is too wonderful for me;
It is high, I cannot attain it.
Where can I go from your Spirit?
Or where can I flee from Your presence?
If I ascend to heaven, you are there;
If I make my bed in hell, behold, You are there.
If I take the wings of the morning,
And dwell in the uttermost parts of the sea,
Even there Your hand shall lead me.
If I say, "Surely the darkness shall fall on me,
Even the night shall be light about me;
Indeed the darkness shall not hide from You,
But the night shines as the day;
The darkness and light are both alike to You.
For you formed my inward parts;
You covered me in my mother's womb.
I will praise You, for I am fearfully and wonderfully made;
Marvelous are Your works,
And that my soul knows well.
My frame was not hidden from You,
When I was made in secret,
And skillfully wrought in the lowest parts of the
earth.
Your eyes saw my substance, being yet
unformed.
And in Your book they are all written,
The days fashioned for me,
When as yet there were none of them.
How precious also are Your thoughts to me, O
God!
How great is the sum of them!
If I should count them, they would be more in
number than the sand;
When I awake, I am still with You.
And then David asks for God to come to His aid. I am not presenting this as a formula for prayer, but as a way for us to remember who God is and our relationship to Him, as a comfort and confidence and hope.
