From the heavens you uttered judgment; the earth feared and was still, when God arose to establish judgment, to save all the humble of the earth. Selah
The attitude being described here is worship in reverential awe. The entirety of Psalm 76 sings of God's protection of His people. It worships The Lord for His power. It warns those who would be the enemies of God to reconsider their positions because of God's mighty power and His care for His people.
God's power is greater than mankind's power. Even as I write this, the Midwest is being warned of a major winter storm bearing down on the area. We can prepare for it, but we cannot stop it. The natural world which God made and put into motion is greater than us and God still uses it to establish His power and call us to consider our own weakness. The heavens are still the Lord's.
And when God brings an outcome, it is in keeping with His heart and His character. Judgment does not happen for judgment's sake alone, but also to assist "the humble of the earth". God brings justice to all. We try to do that with difficulty in society. God does it perfectly and should be loved and worshiped as a result.
