Spurgeon · Verse 4
I have not sat with vain persons. True citizens have no dealings with traitors. David had no seat in the parliament of triflers. They were not his boon companions at feasts, nor his advisers in council, nor his associates in conversation. We must needs see, and speak, and trade, with men of the world, but we must on no account take our rest and solace in their empty society. Not only the profane, but the vain are to be shunned by us. All those who live for this life only are vain, chaffy, frothy men, quite unworthy of a Christian's friendship. Moreover as this vanity is often allied with falsehood, it is well to save ourselves altogether from this untoward generation, lest we should be led from bad to worse and from tolerating the vain should come to admire the wicked. Neither will I go in with dissemblers. Since I know that hypocritical piety is double iniquity, I will cease all acquaintance with pretenders. If I must need walk the same street, I will not enter the same door and spend my time in their society. The congregation of the hypocrites is not one with which we should cultivate communion; their ultimate rendezvous will be the lowest pit of hell, let us drop their acquaintance now! for we shall not desire it soon. They hang their beads around their necks and carry the devil in their hearts. This clause is in the future tense, to indicate that the writer felt no desire to begin an acquaintance with the characters whom up till then he had shunned. We must maintain the separated path with more and more circumspection as we see the great redemption day approaching. Those who would be transfigured with Jesus, must not be disfigured by conformity to the world. The resolution of the psalmist suggests, that even among professed followers of truth we must make distinctions, for as there are vain persons out of the church, so there are dissemblers in it and both are to be shunned with scrupulous decision.
