Restore us, shine upon us

Psalm 80:1-7
Restore us, O Lord; make your face shine upon us, that we may be saved. Three of this sentences separate  this psalm into three parts.
First part is asked the Lord hear us prayer. He is the leader of Israel, please awake your mighty.
Second part is how long the anger of the Lord against them, they were weeping  and be source of contention to their neighbor, then enemies mock them.
Why?
Israel was lost protection so became the source of contention of their neighbor, it was serious misery.
Psalmist confess the Lord is their God, asked for His coming, pay attention to them, so asked the Lord turn his face shine upon them. The Lord is the light so when he turn to them the light is come upon them.
Restore our mind and heart to the Lord is the basic step to pray to God. It needs the mighty power of the Lord reminds us,  strengthens us.
Why?
When a man felt shame and need help, he has chance to be restore, another point is which one is his source of rescue. Let every people knows only the Lord is the savior.
