Like Psalm 95, the Venite, Psalm 100, the Jubilate Deo is an invitatory psalm, a call to “all lands” to join in enthusiastic and joyful corporate worship of the Lord, and to “serve [him] with gladness”; who made all things, and who made the faithful out of every nation his people, by freely setting his watchful saving love upon them: “it is he that hath made us, and not we ourselves; we are his people and the sheep of his pasture”. (Because of this invitation to “all lands” it has special resonance in the season of Epiphany when we celebrate Christ’s manifestation to all nations as their Savior and Lord.) He is the “good shepherd”, who lays down his life for the sheep (John 10:15). We are drawn to “enter his courts with thanksgiving, and his gates with praise”, in gratitude not just for the gifts we receive from him but for the giver himself, whose character is revealed as one his unfailing and inexhaustible goodness: “for the Lord is gracious, his mercy is everlasting, and his truth endureth from generation to generation”. This is a goodness we can rely on. Such a God as this can be trusted implicitly for life and salvation, through thick and thin: still more, he stirs in us a grateful love that unites us to him in fellowship and communion.
