Does God Protect His Word (part 5)?

Proverbs 30:5-6, "Every word of God is tested; He is a shield to those who take refuge in Him. Do not add to His words or He will reprove you, and you will be proved a liar."

Tested:

"Every thing that God has pronounced, every inspiration which the prophets have received, is pure, without mixture of error, without dross. Whatever trials it may be exposed to, it is always like gold: it bears the fire, and comes out with the same lustre, the same purity, and the same weight." (Adam Clarke, 1762–1832)

"The whole of Scripture is pure, free from all falsehood and error; coming from the God of truth, who cannot lie, and therefore called "the Scriptures of truth": every promise is pure as well as precious, made without dissimulation, faithfully performed, and all yea and amen in Christ; every doctrine is pure, free from the mixtures and inventions of men; the sincere milk of the word; consistent and all of a piece, not yea and nay; and tending to promote purity of heart and life; wholesome words, and doctrines according to godliness." (John Gill, 1697-1771)

"You must not expect the full knowledge of Divine mysteries from me, nor from any man, but from the word of God." (John Wesley, 1703-1791)

Do not add:

"Men are not to mingle revealed truth with their own imaginations and traditions. In speculating on the unseen, the risk of error is indefinitely great, and that error God reproves by manifesting its falsehoods." (Albert Barnes, 1798–1870).

"You can no more increase their value by any addition, than you can that of gold by adding any other metal to it. Take care that you do not any thing that this word forbids, nor leave undone any thing that it commands: for this is adding and diminishing in Scripture phrase." (Clarke, above)

"Add thou not unto his words, because they are pure and perfect. This forbids the advancing of any thing, not only in contradiction to the word of God, but in competition with it; though it be under the plausible pretence of explaining it, yet, if it pretend to be of equal authority with it, it is adding to his words, which is not only a reproach to them as insufficient, but opens a door to all manner of errors and corruptions; for, that one absurdity being granted, that the word of any man, or company of men, is to be received with the same faith and veneration as the word of God, a thousand follow. We must be content with what God has thought fit to make known to us of his mind, and not covet to be wise above what is written." (Matthew Henry, 1662-1714)

"lest he reprove thee; that is, God; either by words or by blows, by threatenings and denunciations of his wrath and displeasure; or by chastisements and corrections for such daring pride, blasphemy, and wickedness; those who add to his words, he threatens to add plagues unto them, Rev 22:18; and thou be found a liar; a forger, speaker, and spreader of doctrinal lies, such doctrines as are contrary to the word of truth; not being built on that, but upon human inventions, and additions to it." (Gill, above)
