By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went. (Hebrews 11:8)
For the experience here referred to see on Gen. 12:1-5.
Obeyed.
He believed what God told him and acted accordingly. His faith found expression in faithful obedience.
Not knowing whither.
According to Gen. 12:5 Abraham and his family “went forth to go into the land of Canaan.” This does not necessarily mean that he knew at the time of his departure what his destination was to be. He simply “went forth to go into [what turned out to be] the land of Canaan.” Obviously God instructed him as to the direction in which he was to set out and the route he was to follow.
