Genesis 21:22-34 

In this lesson, Abraham has his second encounter with Abimelech (a Philistine king).  It was much different than their first meeting four years earlier, which had been a humiliating experience for Abraham (he was rightly reproved by the king for lying about his relationship with Sarah).  This second encounter found Abraham in a much improved spiritual condition.  The two make a peace treaty, which is ratified with sacrifices, witnesses, and promises.  The treaty lasted 70 years; interestingly the one who broke it was Isaac, and he did so by repeating the sin of his father - he lied about his relationship with Rebekah!  Amazing.

Genesis 21:11-21

One of the most difficult separations Abraham faced in his life (and he faced many) was his separation from Ishmael, his illegitimate son born by Sarah's Egyptian handmade, Hagar.  The separation was necessary for the accomplishment of God's purposes for both Isaac and Ishmael, so Abraham obeyed by casting out both Hagar and Ishmael, even though it broke his heart.

It is wonderful to learn how the Lord God took care of Ishmael (and Hagar) and blessed him!  It is also interesting to learn how the Apostle Paul used the separation of Hagar and Ishmael from Abraham, Sarah, and Isaac as an allegory involving Law and grace (Galatians 4:21-31)!  A lot to discover in this deep lesson!

Genesis 21:1-10 

After reading about the destruction of Sodom in chapter 18, the sad end of Lot in chapter 19, and Abraham's shameful return to the sin of lying about Sarah in chapter 20, it is great to break out in laughter in the beginning of chapter 21.  This lesson begins with the birth of Isaac, whose name means "laughter".  This promised son was a long time coming, but when he was finally born, he brought immense joy into the life of his family . . . well, with one exception, and his name was Ishmael.  

In this lesson, "Isaac and Ishmael," we look at the birth delight (21:1-7), the brotherly discord (21:8-10), and some amazing typology (Isaac as a type of Christ) in a section entitled Bible Depths.

Genesis 20:1-18

This lesson is the account of the third major failure of Abraham.  Sadly, it was a repeat of his first failure, when he purposely hid the truth that Sarah was his wife and not just his sister.  If even a great man like Abraham (the "father of faith" and "friend of God") sins, we certainly know none of us are exempt!  One of the reasons (among multitudes) we know the Bible is truly God-inspired is because it always speaks the truth about people, even "the best" of God's people.  We read about Noah's drunkenness, Moses' temper, David's adultery, and Peter's denials.  

We look at Abraham's iniquity, God's intervention, and King Abimelech's integrity and inquisition of Abraham and Sarah.  In this account, we find the first healing miracle recorded in the Bible!  Find out what it was and on whom it was performed!

Genesis 19:15-38

This is the second of a two-part lesson on Lot, "Friend of the World".  In lesson 43, we learned that Lot was a compromised believer, an ineffective leader, and a powerless witness for the Lord.  He was also a double-minded man.  He lingered too long in Sodom and longed for Zoar (another worldly city).  He also failed as a husband and was a pitiful father.

We need to learn from Lot's serious mistakes, for the Lord warned that the days preceding His Second Coming will be "as it was in the days of Lot" (Luke 17:28).  If you know anything about the immorality of Sodom, you know we are "there" today!
