Early in this Chapter, God tests Abraham by demanding his son of promise, Issac.  God was refining Abraham’s character by commanding his loyalty and charging him to live in obedience.  Anytime God tests us it’s for our ultimate benefit and good.  Testing and sacrifice are just part of our journey towards self-discipline and holiness.  Sacrifice is offering back to God the only thing I have to give… a love-gift of myself…of giving the best I have to the One I love the most.
