When thou sawest a thief, then thou consentedst with him." Moral honesty cannot be absent where true grace is present. Those who excuse others in trickery are guilty themselves; those who use others to do unjust actions for them are doubly so. If a man be ever so religious, if his own actions do not rebuke dishonesty, he is an accomplice with thieves. If we can acquiesce in anything which is not upright, we are not upright ourselves, and our religion is a lie. "And hast been partaker with adulterers." One by one the moral precepts are thus broken by the sinners in Zion. Under the cloak of piety, unclean livers conceal themselves. We may do this by smiling at unchaste jests, listening to indelicate expressions, and conniving at licentious behaviour in our presence; and if we thus act, how dare we preach, or lead public prayer, or wear the Christian name? See how the Lord lays righteousness to the plummet! How plainly all this declares that without holiness no man shall see the Lord! No amount of ceremonial or theological accuracy can cover dishonesty and fornication; these filthy things must be either purged from us by the blood of Jesus, or they will kindle a fire in God's anger which will burn even to the lowest hell.
