Charles H. Spurgeon on Psalms 119:117

Hold thou me up: as a nurse holds up a little child. "And I shall be safe, "and not else; for unless thou hold me up I shall be falling about like an infant that is weak upon its knees. We are saved by past grace, but we are not safe unless we receive present grace. The Psalmist had vowed to keep the Lord's commands, but here he pleads with the Lord to keep him: a very sensible course of procedure. Our version roads the word "uphold, "and then "hold up; "and truly we need this blessing in every shape in which it can come, for in all manner of ways our adversaries seek to cast us down. To be safe is a happy condition; there is only one door to it, and that is to be held up by God himself; thank God, that door is open to the least among us.

And I will have respect unto thy statutes continually. In obedience is safety; in being held up is obedience. No man will outwardly keep the Lord's statutes for long together unless he has an inward respect for them, and this will never be unless the hand of the Lord perpetually upholds the heart in holy love. Perseverance to the end, obedience continually, comes only through the divine power; we start aside as a deceitful bow unless we are kept right by him that first gave us grace. Happy is the man who realizes this verse in his life: upheld through his whole life in a course of unswerving integrity, he becomes a safe and trusted man, and maintains a sacred delicacy of conscience which is unknown to others. He feels a tender respect for the statutes of the Lord, which keeps him clear of inconsistencies and conformities to the world that are so common among others, and hence he is a pillar in the house of the Lord. Alas, we know some professors who are not upright, and therefore they lean to sin till they fall over, and though they are restored they are never safe or reliable, neither have they that sweet purity of soul which is the charm of the more sanctified who have been kept from falling into the mire.
