Read Faith Is Creative, by Alistair Begg, at One Place.
"The world is constantly creating and inventing; genius serves all the purposes of human desire: Can't faith invent too and by some creative means reach the people who are strangers to the Gospel? It was the presence of Jesus that stirred this victorious courage in the four friends of the paralytic. Is the Lord still present among us? Have we seen His face for ourselves this morning? Have we felt His healing power in our own souls? If so, then through the door or the window or the roof let us overcome every hindrance in bringing others to Jesus."
Being unable to get to Him because of the crowd, they removed the roof above Him; and when they had dug an opening, they let down the pallet on which the paralytic was lying.
