Psalms 27:4

While we distinguish Christ here also, as our glorious Head, thus seeking, above all things, communion with the Father; and while we behold the blessed Jesus spending whole nights in prayer to God (Luke 6:12), we may, by virtue of our union with him, and interest in him, see how delightful an evidence this becomes of our new life. My brother, if the Lord Jehovah be indeed your light and salvation, then this one thing will also be the one thing needful, and the grand desire of your soul: no one, who hath once seen the King in his beauty, will feel his heart captivated with any other. To contemplate the glory, grace, wisdom, love, and faithfulness, in God the Father, as manifested most eminently in the redemption by his dear Son; to behold the glories of Christ's person, the infinite beauties in himself, and the infinite riches in his salvation; And to admire and adore the love, and grace, and condescension of God the Spirit: whoever hath thus seen Jehovah, in his threefold character of person, will find, under Christ, a heart constrained, by the same influence, to desire this one thing, and this one only, as the sum total of all happiness.
