Many of us right now are identifying with Asaph. We are at the beginning of Psalm 77:

¹ I cry out to God; yes, I shout.
    Oh, that God would listen to me!
² All night long I prayed, with hands lifted toward heaven,
    but my soul was not comforted.
³ I think of God, and I moan,
    overwhelmed with longing for his help.
⁴ You don’t let me sleep.
    I am too distressed even to pray!
⁵ I think of the good old days,
     long since ended,
⁶ when my nights were filled with joyful songs.
   I search my soul and ponder the difference now.
⁷ Has the Lord rejected me forever?
   Will he never again be kind to me?
⁸ Is his unfailing love gone forever?   
⁹ Has God forgotten to be gracious?

How do we have the mind of Christ in this? 

Going back is not happening, but remembering the faithfulness of God in our former days will get us through. It’s as though Asaph had a moment of revelation. Perhaps he thought…”WAIT! I have a choice! I can choose to dwell on what I have lost and be downcast OR I can choose to dwell on all those times in my past where God led me through into a place of joy.” YES! We can choose!

Now we see an abrupt change in his song.

¹¹ But then I recall all you have done, O Lord;
    I remember your wonderful deeds of long ago.

¹² They are constantly in my thoughts.
    I cannot stop thinking about your mighty works.
¹³ O God, your ways are holy,
    Is there any god as mighty as you?
¹⁴ You are the God of great wonders!
   You demonstrate your awesome power among the nations.

[Then he goes into detail of God’s mighty interventions.]

¹⁹ Your road led through the sea,
   your pathway through the mighty waters— a pathway no one knew was there!
²⁰ You led your people along that road like a flock of sheep,
   with Moses and Aaron as their shepherds.”

Isaiah 43:19 says:

“For I am about to do something new. See, I have already begun! Do you not see it?
I will make a pathway through the wilderness. I will create rivers in the dry wasteland.”
