Epistle to Diognetus

This faith if thou also desirest, apprehend first full knowledge of the Father.

Ταύτην καὶ σὺ τὴν πίστιν ἐὰν ποθήσῃς, καὶ λάβῃς πρῶτον μὲν ἐπίγνωσιν πατρός...

For God loved for whose sake He made the world, to whom He subjected all things that are in the earth, to whom He gave reason and mind, whom alone He permitted to look up to heaven, whom He created after His own image, to whom He sent His only begotten Son, to whom He promised the kingdom which is in heaven, and will give it to those that have loved Him.
