Fear the Lord is necessary

Psalm 76:1-12
You alone are to be feared. Who can stand before you when you are angry?
Surely your wrath against men bring you praise, and the survivors of your wrath are restrained- and with the remainder of wrath you arm yourself.
The Lord is the only one- His name is great, He pronounced judgement. Make vow to the Lord and full fill them
The Lord save all the afflicted of the land,breaks the spirit of rulers; he is feared by the kings of the earth.
Why?
Fear the Lord brings praises to the Lord, all His people need to fear the Lord.
No one can stand before the Lord when God are angry.
Fear the Lord, his judgement and righteous. So we like to follow his command to avoid the punishment from God.
How?
Reverence to the Lord from fear the Lord, love the Lord for his mercy deeper and longer than his wrath.
