In Christ's parable teaching the same principle is seen as in His own mission to the world. That we might become acquainted with His divine character and life, Christ took our nature and dwelt among us. Divinity was revealed in humanity; the invisible glory in the visible human form. Men could learn of the unknown through the known; heavenly things were revealed through the earthly; God was made manifest in the likeness of men. So it was in Christ's teaching: the unknown was illustrated by the known; divine truths by earthly things with which the people were most familiar.

Det samme princip, som lå til grund for Kristi komme til denne verden, ses i hans undervisning i lignelser. Kristus påtog sig vor natur og boede blandt os, for at vi kunne komme til at kende hans guddommelige karakter og liv. Guddommen blev åbenbaret i menneskelighed, den usynlige herlighed i den synlige menneskelige skikkelse. Menneskene kunne lære af det ukendte gennem det kendte, det himmelske blev åbenbaret gennem det jordiske; Gud selv åbenbarede sig i menneskeskikkelse. Dette var også tilfældet i Kristi undervisning, det ukendte blev illustreret med det kendte, guddommelige sandheder med jordiske ting, som menneskene var fortrolige med.
