What Abraham was able to see was that this test was about loving God supremely. In the end the Lord said to him, “Now I know you fear God.” In the Bible, this does not refer so much to being “afraid” of God as to being wholeheartedly committed to him. In Psalm 130:4, for example, we see that “the fear of God” is increased by an experience of God’s grace and forgiveness. What it describes is a loving, joyful awe and wonder before the greatness of God. The Lord is saying, “Now I know that you love me more than anything in the world.” That’s what “the fear of God” means.
