The Psalmist is saying that the law is not a suggestion that is helpful to you.  The law calls for an eternity after the blessing or the curse. If Gods law says something is true, then believe it and follow it.

Gods law is not a suggestion that people should be good, it is a description of what people should not do. The law rightly demands eternity beyond blessings or curses.

God gave the law of protecting the rights of His people. He knew the wicked would change the law to do violence. It is why the law only curses all offenses.

When we do not teach ten commandments to children we are not evading punishment. We are making our lives dangerous. We are asking them to kill us.

40 5 “There are many, O Lord my God, the miracles that You have done. Nobody can tell you the things you have planned for us; if I spoke to him and told him there would be too many to tell. ”He teaches that God's law is never without a covenant. 

The Psalmist loves law because it has curses of protection and a covenant swearing God will work for us. The law he pronounces brings him joy. The heart of his desire.

 God has to follow the rules of society just like everyone else. We can't be responsible for what we do unless we control what we do. What is the law that cannot be settled?  God wanted to tell any people who walked the earth what they could and couldn't do because he loved them.

God created the world and made authoritative statements about it because he wanted people to be able to understand that he is God.

We can't be responsible for the whole earth if we can't settle the eternal law. 

 God cannot do what he wants without regulating the law. We cannot be responsible if we don't choose what we want to be responsible for. 

Therefore, the psalmist adequately expresses direct control of the moral law through the utterance of the identity rooted in the death of the self. v 6-8 Blessing of the Covenant Society v 9.10 Curse of the Covenant v 11-15 The Unity of the Covenant Society on Earth v 16 In this way, the psalmist controls the law by pronouncements.

40 8 "I want to do your will, oh my God, your law is in my heart." The Psalmist carefully teaches that the law is not a constructive suggestion. The law rightly calls for eternity beyond the blessing or the curse. Wherever the law speaks, follow the blessing of indemnity and the prevention of curse. Careful teaching of the law adequately ensures eternal blessing. 5 “Many, O Lord my God, are the wonders which you have done. The things that you have planned for us, no one can tell you; if I spoke to him and told him, they would be too many to say.” He teaches the law of God is never without a covenant. God cannot be responsible for doing what he wants without regulating the law. We cannot be responsible without dominating what we select. How can we be responsible for the whole earth if we cannot settle the eternal law? This is why God made authoritative statements on the created earth. Therefore, the Psalmist adequately expresses direct control over the moral law by pronouncing the established identity in self-death. v 68 Blessing of the covenant community v 9.10 covenant curse v 1115, unity of the covenant community on earth v 16 In this way, the psalmist controls the law with statements.
