16. But to the wicked God says: "What right have you to recite my statutes or take my covenant on your lips?
17. For you hate discipline, and you cast my words behind you.
18. If you see a thief, you are pleased with him, and you keep company with adulterers.
19. "You give your mouth free rein for evil, and your tongue frames deceit.
20. You sit and speak against your brother; you slander your own mother's son.
21. These things you have done, and I have been silent; you thought that I was one like yourself. But now I rebuke you and lay the charge before you.
22. "Mark this, then, you who forget God, lest I tear you apart, and there be none to deliver!
23. The one who offers thanksgiving as his sacrifice glorifies me; to one who orders his way rightly I will show the salvation of God!"

These verses rightly concerns Christendom  - all those that call themselves Christian, when most have not put their faith and trust in Jesus Christ, that he died, was buried and rose again three day's later, for the sake of their sin. Christendom comprises the tares and wheat (Matthew 13:25-30) in Jesus' description of the Mystery Kingdom program. The tares are the apostate, and wicked and the wheat are the born again Christian.

CS Spurgeon writes of this Psalm: 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 endeavours 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!
