God's Eye Upon His Servant

How does this section of the Psalm emphasis Spiritual Sight by the Holy Spirit? Does the Kingdom of God come with physical observation? How does the term ‘foolish people’ apply to all without Spiritual Sight? According to the law can anyone satisfy justice down to the very intent of the law? How was the law given as an expression of love for Who God is? When was the very first Gospel message preached? Why did Christ have to be both complete man and complete God? Did God turn His back on His Son ever, even for a split second? How is the expression of the Hebrew language indicating the work was done already as an emphasis misleading as to the necessary time element to the actual accomplishment of Christ’s death? How did the precept and penalty of the law both have to be finished in order for justification to be complete?
