My Goodness Extendeth Not To Thee

[David] recognizes his solemn dedication of himself to God as his God: "O my soul! thou hast said unto the Lord, Thou art my Lord, and therefore thou mayest venture to trust him." It is the duty and interest of every one of us to acknowledge the Lord for our Lord, to subject ourselves to him, and then to stay ourselves upon him. Adonai signifies My stayer, the strength of my heart. This must be done with our souls: "O my soul! thou hast said it." Covenanting with God must be heart-work; all that is within us must be employed therein and engaged thereby. Those who have avouched the Lord for their Lord should be often putting themselves in mind of what they have done. "Hast thou said unto the Lord, Thou art my Lord? Say it again then, stand to it, abide by it, and never unsay it. Hast thou said it? Take the comfort of it, and live up to it. He is thy Lord, and worship thou him, and let thy eye be ever towards him." - Matthew Henry
