Hagar and Ishmael Cast Out
God is not looking to hurt us in any way. He tells us not to sin to keep us from harming ourselves and other; He is not out to prevent us from having any fun. If you are in trouble, call out to Him. If you are not in trouble, then continue to walk faithfully with Him.
Isaac Will Your Seed Be Called
Genesis 21: 11-21
Gen 21:11 And the thing was very grievous in Abraham's sight because of his son.
Gen 21:12 And God said unto 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.
Gen 21:13 And also of the son of the bondwoman will I make a nation, because he is thy seed.
Gen 21:14 And Abraham rose up early in the morning, and took bread, and a bottle of water, and gave it unto Hagar, putting it on her shoulder, and the child, and sent her away: and she departed, and wandered in the wilderness of Beersheba.
Gen 21:15 And the water was spent in the bottle, and she cast the child under one of the shrubs.
Gen 21:16 And she went, and sat her down over against him a good way off, as it were a bowshot: for she said, Let me not see the death of the child. And she sat over against him, and lift up her voice, and wept.
Gen 21:17 And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he is.
Gen 21:18 Arise, lift up the lad, and hold him in thine hand; for I will make him a great nation.
Gen 21:19 And God opened her eyes, and she saw a well of water; and she went, and filled the bottle with water, and gave the lad drink.
Gen 21:20 And God was with the lad; and he grew, and dwelt in the wilderness, and became an archer.
Gen 21:21 And he dwelt in the wilderness of Paran: and his mother took him a wife out of the land of Egypt.
