In Psalms, chapter forty, verse eight, the New Testament relates to the theme with Hebrews ten, verses five through ten, and quotes verses six to eight of Psalms forty and applies them to Jesus Christ. Verse six speaks of the inadequacy of the old covenant, and verse seven refers to the coming of Christ into the world to bring redemption, as in Luke twenty-four, verse twenty-seven, and John five, verse forty-six. The Son of God’s obedience to the Heavenly Father and His preaching of righteousness is Psalms forty, verses eight through ten. They are similar to Philippians two, verses five through eight.
The motto of Jesus’ whole life was in Hebrews ten, verse nine, “Then said he, Lo, I come to do thy will, O God. He taketh away the first that he may establish the second.” It is by Christ’s obedience unto death that we have been sanctified, as in Hebrews ten, verse ten, so that the law of God may be in our hearts as in Hebrews ten, verse sixteen. Therefore, every believer must also affirm these words of Christ in their own life, saying, “Lo, I come to do thy will, O God.”
The theme under Delight in the Will of the Lord depicts the believer doing this from their heart. The obedient faith that God desires is one that sincerely delights in following God’s will and manifests that joy by striving to hide God’s Word in their heart, as in Psalms one hundred and nineteen, verse eleven, and John fifteen, verse seven, respectively. The difference between believers and religious people is the heart toward the Almighty God. The saints who love the Lord will delightfully be doers of the Word and will not just obey to get a return from the Lord. Delight starts from the heart.
