Albert Barnes Commentary Psalms 50:22

"Now consider this, ye that forget God, Lest I tear you in pieces, and there be none to deliver:" — Psalms 50:22 (ASV)

Now consider this - Understand this; give attention to this. The word “now” does not adequately express the force of the original. The Hebrew word is not an adverb of “time,” but a particle denoting “entreaty,” and would be better rendered as, “Oh, consider this;” or, “Consider this, I urge you.” This matter is presented to them as deserving their most solemn attention.

You that forget God - Who really forget Him, even though you profess to be engaged in His worship; who, in the midst of the forms of religion, are actually living in complete forgetfulness of the just claims and of the true character of God.

Lest I tear you in pieces - This is language derived from the fury of a ravenous beast tearing its victim limb from limb.

And there be none to deliver - As no one can do when God rises up in His wrath to inflict vengeance. None would venture to Interpose; none could rescue from His hand.

There is a point of time for all sinners when no one, not even the Redeemer—the great and merciful Mediator—will interpose to save; when the sinner will be left to be dealt with by simple, pure, unmixed and unmitigated justice; when mercy and kindness will have done their work for them in vain; and when they will be left to the mere desert of their sins. At that point, there is no power that can deliver them.
