Alone in a house of unlikes: a solitude that is thrust upon you. But then out comes art. Is art always the offspring of spiritual poverty? No. God made the Heavens and the Earth. But Lewis speculates that in creating, it's possible that God made in Himself a want only we could fulfill. Only omnipotence could do that. Perhaps that is what is meant by this: God saw the crucifixion in creating the first nebula. Suffering and art mingle. It's almost a prerequisite that the creation of art is given birth by prior birth pains: and so God impregnated Himself with creation.
