It is not matter which I adore; it is the Lord of matter, becoming matter for my sake, taking up His abode in matter and working out my salvation through matter. For “the Word was made Flesh, and dwelt amongst us.” (Jn. 1.14) It is evident to all that flesh is matter, and that it is created. I reverence and honour matter, and worship that which has brought about my salvation. I honour it, not as God, but as a channel of divine strength and grace.
