Charles H. Spurgeon on Psalms 24:4

Now we come to the four conditions requisite to render such an ascent possible. 1. Abstinence from evil doing: "He that hath clean hands." 2. Abstinence from evil thought: "and a pure heart." 3. Who does that duty which he is sent into the world to do: "That hath not lifted up his mind unto vanity;" or, as it is in the Vulgate, "Who hath no received his soul in vain." And, 4. Remembers the vows by which he is bound to God: "nor sworn to deceive." And in the fullest sense, there was but One in whom all these things were fulfilled; so that in reply to the question, "Who shall ascend into the hill of the Lord?" He might well answer, "No man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven." John 3:13. "Therefore it is well-written," says St. Bernard, "that such an High Priest became us, because he knows the difficulty of that ascent to the celestial mountain, he knows the weakness of us that have to ascend." Lorinus and Bernard, quoted by J. M. Neale.
