The context of these verses have to do with one, who, calling on the Lord, is assured that his voice is heard, relying on the grace of God in forgiveness. He then expresses confidence in the Lord, as he waits for the redemption of Israel (vs 8).
This psalm is identified as a 'song of degrees', indicating that it was sung by pilgrims as they ascended up to Jerusalem to worship at the Temple.
My attention is drawn to verses 5 & 6, because they have to do with 'waiting'...something which I am learning to do.
I am reminded of my days (and nights) spent as a security guard. A part of the responsibilities of the night shift (11 pm -7 am), was to raise the American flag at daybreak. Sometimes, the nights seemed extraordinarily long and we waited impatiently for the dawning. Gradually, the stars would fade and the things hidden in the darkness began to take shape, becoming more clearly seen as the day dawned. Though the nights sometimes seemed uncommonly long, the sun always rose, dispelling the darkness.
I came across the following observation by G. Christian Weiss in his book THE PERFECT WILL OF GOD. Quoting from James McConkey, he wrote, "Sometimes our perplexity is so great that it seems no guidance will ever come...the psalmist has a precious message in his word about night-watchers. 'My soul waiteth...' (Ps 130:6).
"How do men wait...for the dawn...?
1. They watch in darkness.
2. They watch for that which comes slowly.
3. They watch for that which is sure to come.
4. They watch for that which, when it does come brings the light of day."
...and so it is for those who await God's guidance...as well as for those who await His Coming!
Maybe you'd like to find the words to "It Will Be Worth It All" and sing it through the day as a gentle reminder to wait on the Lord.
