Psalms 107:19

Psalms 107:19. Then they cry unto the LORD in their trouble,

Fools though they are, they have sense enough to do this.

Psalms 107:19. And he saveth them out of their distresses.

So that a true prayer from one who is near unto the gates of death is a prevailing prayer. We earnestly urge all to repent long before they come to a dying bed, but if they are on a dying bed, if they are literally near unto the gates of death, here is evidence that, if they cry unto the Lord in their trouble, he will not close his ears or his heart to their prayer.
