Why this is important: David knows a lot about God’s plan for countries and kingdoms. We can plan and scheme all we want. God has a Kingdom. Jesus is King.
Our plans don’t mean anything. It is all about what God wants. I must get this in my heart and soul. I must act on God’s plan, not my own. It isn’t about what I want.
David knows that:
- God is God. He knows everything and is all powerful.
- God is in control.
- God’s plan will hold up and be accomplished. God chooses us. We do not choose Him.
- We are blessed when we are “for God”.
Yahweh [the Lord] brings the counsel of the nations to nothing; he frustrates the plans of the peoples. The counsel of Yahweh [the Lord] stands forever, the plans of his heart to all generations. Blessed is the nation whose God is Yahweh [the Lord], the people whom he has chosen as his heritage!
