Obedience and the Fear of God

Genesis 22:15-19 Then the Angel of the LORD called to Abraham a second time out of heaven, and said: 'By Myself I have sworn, says the LORD, because you have done this thing, and have not withheld your son, your only son -- 'blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore; and your descendants shall possess the gate of their enemies. 'In your seed all the nations of the earth shall be blessed, because you have obeyed My voice.' So Abraham returned to his young men, and they rose and went together to Beersheba; and Abraham dwelt at Beersheba.
