Thought from Today’s Old Testament Passage:
And Joshua said unto all the people, Thus saith the Lord God of Israel, Your fathers dwelt on the other side of the flood in old time, even Terah, the father of Abraham, and the father of Nachor: and they served other gods [Josh. 24:2].
When God called Abraham from Ur of the Chaldees, He called him out of a home of idolatry. Terah, his father, we are told here, served other gods.
This raises the question: Why did God choose Abraham and make a nation from him? Let’s consider the background. After the Tower of Babel, man totally departed from the Lord. No one served God—not even Terah the father of Abraham. When God confused the language, the people scattered in every direction, and they took with them a knowledge of the true and living God, which is the reason even pagan tribes today have a knowledge of the true God, although they do not worship Him. There was total apostasy after Babel.
Now what will God do that will be consistent with His person, His attributes, and His character? He could judge the human family and remove it from the earth. He could make the earth as bleak as the moon if He wanted to. But He didn’t. He will recover mankind. He will begin with one man. That man was Abraham, who must have had a desire in his heart to know the living and true God. When God called him, He told him to leave Ur and all his family. Now we know why. Terah was an idolater. God called him away from all that in order to deal with him and make of him a nation through which the Messiah would come into the world. (J.
