A good man leaves an inheritance to his children's children, and the wealth of the sinner is stored up for the righteous.
The Kingdom of God is the consuming focus of all God’s promises to His people. “Thy Kingdom come,” prayed Jesus in His opening statement of the Model Prayer. “Seek first His Kingdom and His righteousness, and all these things will be added to you,” Jesus teaches His disciples (Matthew 6:33).
The “wealth of the sinner” isn’t for the enrichment of the righteous individual, but the advancement of the Kingdom, which is the mission of people made righteous in Christ. God promises that from the world itself will come financial and material resources for the spread of the Kingdom that will transform the world.
