But to the wicked God says: What right have you to declare My statutes, or take My covenant in your mouth, seeing you hate instruction and cast My words behind your back? Ps.50:16-17

Profane professors are often too wise to learn, too besotted with conceit to be taught of God. What a monstrosity that men should declare those statutes which with their hearts they do not know, and which in their lives they openly disavow! Woe unto the men who hate the instruction which they take upon themselves to give. "And castest my words behind thee." Despising them, throwing them away as worthless, putting them out of sight as obnoxious. Many boasters of the law did this practically; and in these last days there are pickers and choosers of God's words who cannot endure the practical part of Scripture; they are disgusted at duty, they abhor responsibility, they disembowel texts of their plain meanings, they wrest the Scriptures to their own destruction. It is an ill sign when a man dares not look a Scripture in the face, and an evidence of brazen impudence when he tries to make it mean something less condemnatory of his sins, and endeavors to prove it to be less sweeping in its demands. How powerful is the argument that such men have no right to take the covenant of God into their mouths, seeing that its spirit does not regulate their lives!
