2 “The heavens tell out the glory of God”. The righteous Evangelists, in whom, as in the heavens, God dwells, set forth the glory of our Lord Jesus Christ, or the glory wherewith the Son glorified the Father upon earth. “And the firmament shows forth the works of His hands.” And the firmament shows forth the deeds of the Lord's power, that now made heaven by the assurance of the Holy Ghost, which before was earth by fear.
