Sing unto God, sing praises to his name: extol him that rides upon the heavens by his name, the LORD, and rejoice before him.
Read Chapter 68
Augustine of Hippo
4. "Lastly, there followeth, "And let just men be joyous, and exult in the sight of God, let them delight in gladness" (ver. 3). For then shall they hear, "Come, ye blessed of My Father, receive ye the kingdom." "Let them be joyous," therefore, that have toiled, "and exult in the sight of God." For there will not be in this exultation, as though it were before men, any empty boasting; but (it will be) in the sight of Him who unerringly looketh into that which He hath granted. "Let them delight in gladness:" no longer exulting with trembling as in this world, so long as "human life is a trial upon earth." Secondly, he turneth himself to those very persons to whom he hath given so great hope, and to them while here living he speaketh and exhorteth: "Sing ye to God, psalm ye to His name" (ver. 4). Already on this subject in the exposition of the Title we have before spoken that which seemed meet. He singeth to God, that liveth to God: He psalmeth to His name, that worketh unto His Glory. In singing thus, in psalming thus, that is, by so living, by so working, "a way make ye to Him," he saith, "that hath ascended above the setting." A way make ye to Christ: so that through the beautiful feet of men telling good tidings, the hearts of men believing many have a way opened to Him. For the Same is He that hath ascended above the "setting:" either because the new life of one turned to Him receiveth Him not, except the old life shall have set by his renouncing this world, or because He ascended above the setting, when by rising again He conquered the downfall of the body. "For The Lord is His name." Which if they had known, the Lord of glory they never would have crucified.
