Is the purpose of this story to tell us that Abraham was a coward lacking in faith that he would use his wife to protect him from death? No, God brought Abraham there to teach Abimelech a lesson.
This incident gave Abimelech a good dose of humility as well and that’s a lesson we would do well to learn. It’s more pleasant to learn from other people’s mistakes than our own.
Why do the prophets, Yeshua the Messiah and His apostles repeatedly refer to Sodom and Gomorrah when talking about judgment and mercy?
From threats of homosexual gang rape of two of God’s messengers to Lot’s offering his two virgin daughters to the mob to Lot’s wife dying from looking back at the destruction of Sodom to Lot’s daughters’ conspiring to get their father so drunk he would get them pregnant, chapter 19 is full of controversy for the modern mind. Actually, there are a lot of parallels between this account and Israel’s miraculous departure from Egypt after Passover.
This chapter is about justice and judgment, just as the book of Revelation is about justice and judgment. God could have taught this lesson to Abraham privately, yet God wants us to know He knew Abraham well. The LORD knew Abraham would keep God’s ways and would also make sure that his family and household would also keep and follow God’s ways. God knew that those who follow Abraham would follow his example.
Abraham obeyed God and had himself and all the men in his household circumcised and they all agreed to do it, including Ishmael. In the flesh, there’s no reason for circumcision, but if you believe in God, there’s every reason for it. Actively trusting God’s words — called “faith” and “belief” — is what makes one righteous.
People find it easy to criticize Sarai and Abram for their impatience in waiting for the son God promised them, but our insight is simply nothing more than hindsight. We aren’t any smarter or more faithful to God than they were.
Apostle Paul used as illustrations the two women, Sarai and Hagar, and the covenants God made with their sons, Isaac and Ishmael. Once you transgress a covenant, you have no hope, unless Someone better than you steps in with a second, better covenant.
The mysterious covenant God enters while Abram sleeps is prefigures a time when Israel was captive in Egypt yet not consumed by it.
