Genesis 19 Lot has a couple angels visit before the destruction of Sodom and Gomorrah.

Genesis 20 Abraham and SarahSay they are brother and sister again.

Genesis 21 Issac is born and God keeps His promise.

So yeah Genesis 19 has a lot going on. Lot has moved into the city. He’s even known among the people. A few chapters ago, he had only planted his tent facing Sodom and now he is living there. What this means is that we have to be careful with what we allow to influence us. What we put in front of our faces and look at or listen to often is going to draw us in. It’s essential to beware of what we watch, listen to, and what friends we make.

These angels come and are solicited by the men in the town for sexual interactions. Lot says something beyond comprehension: he offers his virgin daughters. Maybe this is an indication of how “not in his right mind” he is? Maybe he knew they would not take the offer? Nonetheless, this whole picture is a revelation of how easily immoral sexual activity can lead to lives being destroyed.

Although this is a passage that deals much with God’s displeasure over homosexual activity what is also important to realize is that God had people interceding (Abraham), and even Lot and his family were living there who could have represented Christ to all in the city prior to this day. God doesn’t like for people to misuse sex in any form but He is also patient and seeking to help us know how powerful sex is and how it is intended to point us to Him.

“The Lord is not slow about His promise, as some count slowness, but is patient toward you, not willing for any to perish, but for all to come to repentance.”
2 Peter 3:9 NASB2020

Lot and his family escape and once again we see God’s grace here. Lot is told to go to one city farther away but he says it’s too far and the Angel allows it. It’s crazy to think of all this happening in real time and you’ve got this guy (Lot) saying what’s being asked is too hard. His wife looks back and becomes a pillar of salt. This highlights the danger of looking back/ going back to our past.

I find it interesting that she became a pillar of salt. She wants salt in the city like she should have been. She becomes salt as a testimony now.
Abraham and Sarah conceal the truth about being married when they meet Abimelech. This is another instance of God’s grace as the king says God kept him from sinning. What a wonderful thing! The Lord always make a way of escape but we must be willing to heed the warnings.

“how will we escape if we neglect so great a salvation? After it was at first spoken through the Lord, it was confirmed to us by those who heard,”
Hebrews 2:3 NASB2020

Even in all of this, Abraham and Sarah are blessed. God turns everything around and we see His providence in all of it.

Genesis 21 Abraham was 100 when Isaac was born. God kept His promise. Some promises may take years to pass but God always keeps His word. God didn’t give them a child when it was convenient or when they would expect. God doesn’t do things on our timetable. God gave them a son and orchestrated the timing perfectly for His plan. We must continually trust His timing.

God provides for Hagar and Ishmael. Once again, grace is shown in this story. Who said the OT doesn’t demonstrate grace? God provides for them and blesses them. One thing I see here is that even though they were mistreated by those who were supposed to represent God to them, I’m the disillusionment, they still saw God move and work on their behalf. Followers of God are still human and make grave mistakes. Thankfully we have a God who is greater and still takes care of our deepest needs.
