As for me, I will behold Thy face in righteousness… – Psalm 17:15

Have I not seen my Father’s face here below? Yes, I have, “through a glass darkly,” But has not the Christian sometimes beheld Him, when in His heavenly moments earth is gone, and the mind is stripped of matter? There are some seasons when the gross materialism dies away, and when the ethereal fire within blazes up so high that it almost touches the fire of heaven. There are seasons, when in some retired spot, calm and free from all earthly thought, we have put our shoes from off our feet because the place whereon we stood was holy ground; and we have talked with God! even as Enoch talked with Him so has the Christian held intimate communion with his Father. He has heard His love whispers, he has told out his heart, poured out his sorrows and his groans before Him. But after all he has felt that he has not beheld His face in righteousness. There was so much sin to darken the eyes, so much folly, so much frailty, that we could not get a clear prospect of our Jesus. But here the Psalmist says, “I will behold Thy face in righteousness.” When that illustrious day shall arise, and I shall see my Saviour face to face, I shall see Him “in righteousness.” 

My God, I believe I shall stand before Thy face as pure as Thou art Thyself, for I shall have the righteousness of Jesus Christ -there shall be upon me the righteousness of God. “I shall behold Thy face in righteousness.” O Christian, canst thou enjoy this? Though I cannot speak about it, dost thy heart meditate upon it? To behold His face forever; to bask in that vision! True, thou canst not understand it; but thou mayest guess the meaning. To behold His face in righteousness! ~ C.H. Spurgeon
