"The law of the Lord is perfect, reviving the soul." Psalm 19:7
The law of the Lord is perfect because it comes from our Creator-wise God. I would also want to mention the opening of this Psalm because it is about Creation.
"The heavens are telling the glory of God, and the firmament declares his handiwork" Psalm 19:1
The psalmist mentions in the same breadth that the God who created the world is also the same God who gave us law. There must be wisdom in keeping the law; yes, it will revive your soul! You could reflect on the Ten Commandments and see the devastation that comes from not obeying them. On the other hand, by keeping them, your life will be better off. My message on Sunday will delve deeper into this psalm with insights about "reviving your soul."
In preparation I would encourage you to read and contemplate on the entire psalm. It is only 14 verses. Blessings to you in your preparation and worship this Sunday.
