The second century Christian who wrote a letter to his friend, Diognetus, urging him to become a Christian, ended his letter this way:
"God loved the race of men. It was for their sakes that he made the world; it was to them that he gave dominion over everything in it. On them he bestowed reason and understanding, and they alone received permission to lift their eyes to him. He formed them in his own image; he sent his only-begotten Son to them; he promised them the kingdom of heaven, and to those who have loved him he will surely give it. Once you have grasped these truths, think how your joy will overflow, and what love you will feel for him who loved you so."
