A reciprocal relationship between God and humanity is both the condition and the content of Christian worship. Once God, by an irreducible act of will and for the irreducible motive of love, brings a responsive creature into being, He is seeking to draw such a creature into a communion with Himself which will be both the creature’s salvation and the realization of His own purpose. In worship we take in the outpouring of God’s creative and redemptive love, and we offer in return our thanks and supplications. In this personal exchange we are coming into the moral and spiritual likeness of our Lover. This transformation is our glorification in both the objective and the subjective senses: by grace we are being made partakers of the divine nature, and in humility God is being enriched by the requital of His love on the part of His creatures. Our being changed from glory into glory is itself for the greater glory of God.
