Isaías 45

Isaías 45:7

Ever desiring to become more completely known to us and to incite our minds to his worship, he said, "I am the Lord who made the light and created the darkness," that we may not think that some other unknown One was the artificer of those alternations whereby the nights and days are regulated; but rather, and with greater truth, we may acknowledge God as their Creator. — ON THE TRINITY 3:5
