God's glory is the visible manifestation of his perfections shining forth in this world. In Psalm 29, written by King David, God displays his glory in a number of ways. He shines in heaven in the glory of his holiness, as David demands all the angels of heaven to worship him. God thunders in the storm and displays the glory of his power, and he calls us to acknowledge before the world that he is the creator. God sits as king over the flood, displaying the glory of his sovereignty. And God dwells among his people, displaying the glory of his love, which is seen most clearly in Jesus Christ bearing the storm of God's judgment in our place. And in him we can draw near to worship God, and find strength and peace.
And we also thank God constantly for this, that when you received the word of God, which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers.
