By faith Abraham, when called to go to a place he would later receive as his inheritance, obeyed and went, even though he did not know where he was going.
It seems so easy when we read it in the Bible. "Oh sure, Abraham..." we say. "He was a man of faith. Went to the promised land, he did, when God asked him to. No questions asked."
We sit back and relax, then God asks us to do something. Maybe it is to be obedient to your boss, even though your boss shows no love for you. Maybe it is to love your spouse without any surety that your spouse will love you in return. It could be that God is asking you to tell the truth, when the truth will bring trouble and pain to the hearers.
According to this verse, Abraham did not know where he was going. He had no surety that it would work out the way he would want it to.
Trust in Him today.
