"And Sarai said unto Abram, Behold now, the Lord hath restrained me from bearing; I pray thee, go in unto my maid; it may be that I may obtain children by her. " (Gen.16:2)
Welcome to the world of surrogate mothers! Of course, what Sarai did seems tame compared to the synthetic, genetic maneuvering that goes on today. Either way, it's still trying to make an end run around the will of God. Did Sarai even hear herself saying, "The Lord hath retrained me from bearing"?
God had told Abraham in Genesis 15:4 that he would produce an heir from his own seed, but evidently, Sarai feared she was too old to carry it. Did she think that the God who was able to enliven the seed of an old man was incapable of bringing it to fruition in the shriveled womb of an old woman?
Bob Jones, Sr. used to say, "It's never right to do wrong to get a chance to do right." Sarai got her "son" by means of her handmaid, Hagar, and he was a heartache to her, Abraham, and Isaac, the son of promise who came later. And the world today lives in the shadow of the enmity that still lies between those two brothers.
The end doesn't always justify the means, and never when the means are wrong; because, more often than not, questionable means produce undesirable ends. God's will can always be done in God's way. If not, it isn't His will.
Faith is living without scheming.
