Galatians 4:30

VERSE 30. Nevertheless what saith the Scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the free woman.

Sarah's demand that the bondwoman and her son be cast out of the house was undoubtedly a blow to Abraham. He felt sorry for his son Ishmael. The Scripture explicitly states Abraham's grief in the words: "And the thing was very grievous in Abraham's sight, because of his son." (Genesis 21:11.) But God approved Sarah's action and said to Abraham: "Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called." (Genesis 21:12.)

St. Bernard was one of the best of the medieval saints. He lived a chaste and holy life. But when it came to dying he did not trust in his chaste life for salvation. He prayed: "I have lived a wicked life. But Thou, Lord Jesus, hast a heaven to give unto me. First, because Thou art the Son of God. Secondly, because Thou hast purchased heaven for me by Thy suffering and death. Thou givest heaven to me, not because I earned it, but because Thou hast earned it for me." If any of the Romanists are saved it is because they forget their good deeds and merits and feel like Paul: "Not having mine own righteousness which is of the law, but that which is through the faith of Christ." (Philippians 3:9.)
