There will be no deception at the last day. The unerring eye of God will discern who are His own people, and who are not. Nothing but true faith shall abide the fire of His judgment.
All spurious Christianity shall be weighed in the balance and found lacking. None but true believers shall sit down at the marriage supper of the Lamb. It shall avail the hypocrite nothing that he has been a loud talker about religion, and had the reputation of being an eminent Christian among men. His triumphing shall be but for a moment. He shall be stripped of all his borrowed plumage, and stand naked and shivering before the bar of God, speechless, self-condemned, hopeless, and helpless. He shall be cast into outer darkness with shame, and reap according as he has sown. Well may our Lord say, “there shall be weeping and grinding of teeth.”
