How frequent is this…and how long…and how energetic?

I cried unto God with my voice,
even unto God with my voice;
and he gave ear unto me.

In the day of my trouble
I sought the Lord….

Is his mercy clean gone for ever?
doth his promise fail for evermore?

I will remember the works of the Lord:
surely I will remember thy wonders of old.

Thy way, O God, is in the sanctuary:
who is so great a God as our God?

Thou art the God that doest wonders….

Thou leddest thy people like a flock….

Psalm 77
