"The word spoken to Abraham. . . . is a call to leave his own land, a summons to a new life, the beginning of an exodus which points him towards an unforeseen future. The sight which faith would give to Abraham would always be linked to the need to take this step forward: faith 'sees' to the extent that it journeys, to the extent that it chooses to enter into the horizons opened up by God’s word."
Pope Francis, Lumen fidei 9.
