"Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with tongs off the alter. And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged" ~ Isaiah 6:6, 7The "seraphim" did not do the cleansing. The Lord used the "seraphim" to handle the live coal from off the altar. We are cleansed by the holy fire of God's love. "For God so loved the world," and then He gave. What Jesus Christ did on Calvary was more than enough to cleanse our lips. To purge even our sins. To take away even our iniquity. Those of us who have seen God in the face of Jesus Christ know something of the depth of that sin. Only God could bear to know it all the way down! And it broke even His heart. But those of us who have seen Christ have at least seen some of our deep need for cleansing. And when we really see it and become honest with ourselves and before God, we welcome the onflying "seraphims" holding the cleansing fire toward our lips. We welcome them and hold up our mouths to be touched and weep softly so as not to miss one word which God is saying to us through this often painful ordeal. Tenderly, surely, God speaks through this difficult person, through this seemingly unbearable time: "While you were yet sinners, I died for you..."
"... this hath touched thy lips; and thine iniquity is taken away, thy sin purged."
