Blessed is the man who does not walk in the counsel of the wicked or stand in the way of sinners or sit in the seat of mockers. But his delight is in the law of the Lord,
and on his law he meditates day and night. He is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither. Whatever he does prospers.
Do not let this Book of the Law depart from your mouth; meditate on it day and night, so that you may be careful to do everything written in it. Then you will be prosperous and successful.
But seek first the kingdom of God and his righteousness, and all these things will be added to you.
Here are some thoughts on the passages above for your consideration. I believe David picked up on key points of the life of Joshua and took them to heart. Both equated a blessed, prosperous and successful life with the delight and meditation of the Book of the law. How do we come into a lifestyle and capitalize on the benefits of law mediation?
God's law is His sovereign rule. Law has to do with government. We know that His government is one with a King and a Kingdom. To meditate on the ruling of God (his law) is to understand the kingdom. We know that the kingdom of God has everything to do with the Spirit. I believe that by mediating on the rulings of the King against the kingdom of darkness and making decrees in the Spirit (prophecy) is one aspect of seeking first the kingdom. I also believe that mediating on the law day and night can now be done by praying and speaking in tongues. Speaking in tongues is done by the Spirit which is kingdom. Another aspect of seeking first the kingdom is to make a concerted effort to speaking in Spirit (kingdom) speech, which must include prophecy. Cheers.
