God has revealed his word to us

Psalm 147:1-20
The great power our Lord has done, he created everything in the world.
It is good to sing praise to our God, how pleasant and fitting to praise him!
The Lord delights in those who fear him, who put their hope in his unfailing love.
God has revealed his word to Jacob, his laws and decrees to Israel.
Here is God the Almighty: the universe, the seasons, the nation, the elements are his to command. His power sets him utterly above and beyond humankind.
Yet his heart goes out to individuals: all who are hurt and unhappy. He takes pleasure in those who love and respect him. And he gives his people his word to live by. Praise the Lord!
Why?
The psalmists drew many images from the natural world of God's creation to express, not just beauty, but suffering too.
The strength of horse or the legs of a man is not pleasant to the Lord, but God delight those who fear him and put his hope in his unfailing love. The Lord is my strength and my hope. We rely on Him and my eyes focus on Him.
The Lord has revealed his word to us, it is written in the Bible. He also reveal general grace and general revelation to all people, but the Lord has revealed special grace and revelation to his people in Bible.
How?
Praise the Lord is worthy!
