The condition of the heart determines the quality of my discernment. If "the heart is waxed gross," the ears will be "dull of hearing," and the eyes will be "closed." My spiritual senses gain their acuteness or obtuseness from my affections. If my love is muddy my sight will be dim. If my love be "clear as crystal" the spiritual realm will be like a gloriously transparent air.

And the awful nemesis of sin-created blindness is this, that it interprets itself as sight. "The light that is in thee is darkness." We think we see, and all the time we are the children of the night. We think it is "the dawn of God's sweet morning," and behold! it is the perverse flare of the evil one. He has given us a will-o'-the-wisp, and we boastfully proclaim it to be "the morning star."

But there is hope for any man, however blind he be, who will humbly lay himself at Jesus' feet. Let this be my prayer, O Lord, "Cleanse Thou me from secret faults." Deliver me from self-deception, save me from confusing the fixed light of heaven with the wandering beacon-lights of hell. And again and again will I pray, "Lord, that I might receive my sight!"
