Buy the truth. – Proverbs 23:23

Then I say, buy only the truth. Do not be throwing away your life, and your abilities, and your zeal, and your earnestness, for a lie. Some are doing it… Multitudes of sermons are preached, very zealously, to propagate falsehoods, and sea and land are compassed to make proselytes, who shall be ten times more children of hell than they were before. Buy only the truth. Do not buy the glittering stuff they call truth. Never mind the label; look to see if it be truth. Bring everything that is propounded as truth to the test, to the trial. If it will not stand the fire of God’s Word, then do not buy it; nay, do not have it as a gift; nay, do not keep it in the house. Run away from it. It doth eat as doth a canker; let it not come near you. Buy only the truth.

“Buy the truth” at any price, and sell it at no price. If you lose your body for it, if you lose not your soul, you have made a good bargain. If you lose your estate for it, yet if you have heaven in return, how blessed the exchange! You certainly will not need for it to lose your peace of mind, but you may lose everything else, and you shall make a good bargain. Come to no terms with Christ. Throw all into the soul-bargain. Let all go, as long as you may but have truth in the doctrine, truth in the heart, and truth in the life, and Christ, who is the Truth, to be your treasure for ever.

Buy all the truth. When you come to the Bible, do not pick and choose. Do not try to believe half of it, and leave out the other half. Buy the truth-that is, not a section of it that suits your particular idiosyncrasy, but buy the whole. Why need you break up pearls and dissolve them? Buy all that is true. One doctrine of God’s Word balances another. He who is altogether and only a Calvinist probably only knows half the truth, but he who is willing to take the other side, as far as it is true, and to believe all he finds in the Word, will get the whole pearl. ~ C.H. Spurgeon
