This psalm closes as it begins with the declaration: “O LORD our Lord, how excellent is thy name in all the earth!” This statement sets the theme for the entire psalm. God establishes His excellence by His working with and blessings to mankind. Much of this psalm looks back to creation and to man’s original place there.
Jesus, in the Sermon on the Mount, begins to introduce a new relationship for the believer—the Sonship of the believer and the Fatherhood of God. This is not the Fatherhood of God and the brotherhood of man in the liberal tone. We have lost our relationship to God as Father by sin. However, it is restored in Jesus Christ. Those who are saved restore their relationship to the Father. Jesus demonstrated this in His relationship with the Father; then, He introduced that same relationship to the believers.
Salt is necessary for life, but too much salt kills. Jesus used salt as a picture of how a small minority in the world accomplishes a great deal of good and what happens when that salt loses its saltiness.
