God is most glorified in us when we are most conformed to His image

“This is the prime way of honouring God. We do not so glorify God by elevated admirations, or eloquent expressions, or pompous services for him, as when we aspire to a conversing with him with unstained spirits, and live to him in living like him.”
Stephen Charnock, The Existence and Attributes of God, 453 cited in Beeke, Puritan Reformed Spirituality, 404.
