“The original meaning of glory has to do with weightiness. The glory of God summarizes the seriousness, the perfection, and the infinite significance of all of the attributes of God. It sums up who He is, in the awesome brightness and weightiness of all His perfections. What does it mean then for us to glorify God? We cannot add to His glory, for He is already perfectly and infinitely glorious. Rather, for us to glorify God means for us to ascribe the glory that is due His Name in worship. It means that we acknowledge His glory by living as though His perfections are as serious and significant as they really are, so that we reflect His glory through a pure mirror. It means that nothing horrifies us more than the thought of bringing dishonor to His glorious Name, and nothing delights us more than to feel His pleasure as we live to the praise of His glory. It also means that we declare His glory among the nations, inviting others to join us in our love affair with His glorious perfection. Glorifying God thus consumes and defines every aspect of our life and witness as well as our worship.”
