So Abram left, just as the Lord had told him to do, and Lot went with him. (Now Abram was 75 years old when he departed from Haran.)
[Gen 12:4 NET]
That was faith. Obedience proved it. Abram did not know where he was going; he had simply the call of God and a promise. But he asked no questions. He did not insist on knowing how his journey would come out, how profitable it would be, just what he would get in exchange for the land he was leaving and the sacrifice he was making. Quietly, without question or hesitation, he arose, cut the ties that bound him to his old home, and departed.
That is the kind of faith all of us should have, whenever God gives us a call and a promise. Some people want to see where they are going before they will begin to follow Christ; but that is not walking by faith at all.
We should not trouble ourselves to know where we are to be led, if only we know that God is leading us. His guidance is safe; and we should be willing to trust him, do precisely what he says, and go just where he leads, without asking any questions. Abraham’s life is a picture of a true “walk with God.”
