Pirkei Avot §avot_03_14: He used to say: Beloved is man for he was created in the image [of God].

He used to say: Beloved is man for he was created in the image [of God]. Especially beloved is he for it was made known to him that he had been created in the image [of God], as it is said: “for in the image of God He made man” (Genesis 9:6). Beloved are Israel in that they were called children to the All-Present. Especially beloved are they for it was made known to them that they are called children of the All-Present, as it is said: “you are children to the Lord your God” (Deuteronomy 14:1). Beloved are Israel in that a precious vessel was given to them. Especially beloved are they for it was made known to them that the desirable instrument, with which the world had been created, was given to them, as it is said: “for I give you good instruction; forsake not my teaching” (Proverbs 4:2).
