Buy the truth, and sell it not… – Proverbs 23:23

Some sell the truth for a livelihood. I pity these far more. “I must have a situation; therefore, I must do what I am told there; I must break this law of God and that, for I must keep my family.” Ah! poor soul, I pity thine unfortunate position, but I pray that thou mayest have grace even now to play the man, and never sell the truth, even for bread.

Some sell the truth for the pleasures of the world. They must have enjoyment, they say, and so they will mingle with the multitude that do evil, and give up their Christian profession.

Others seem to sell the truth for nothing at all. They merely go away from Christ because religion has grown stale with them. They are weary of it, and they go away. I shall put the question painfully to all, Will ye also go away? Will ye to be respectable, will ye to have a livelihood, will ye to have the pleasures of sin for a season, will ye out of sheer weariness-will ye go away? Nay, we can add:

“What anguish has that question stirred,
If I will also go!
Yet, Lord, relying on thy Word,
I humbly answer, No.”

Sell it not; sell it not; it cost Christ too dear. Sell it not; you made a good bargain when you bought it. Sell it not. Sell it not; it has not disappointed you; it has satisfied you, and made you blessed. ~ C.H. Spurgeon
