Here are the notes I made while reading.
17:5 Abraham's name changed and called the father of nations
17:25 Ishmael was 13 when he was circumcised - bar mitzvah ?
19:29 God remembered Abraham and saved Lot and his family
20:2 Abraham again lied about Sarah not being his wife
22:14 Jehovah Jireh - the Lord provides
26:7 Jacob lied about Rebekah being his wife
I guess the thing that stood out to me the most was that both Abraham and Jacob lied about their wives. While it would probably keep the men safe it could have meant in both cases that their wives would be taken as wife, etc by other men. Yet all they thought about were themselves.
Next time satan comes to you (and me) with how many times we have sinned, let's remind him of the men from the bible who did too, but because they repented they were forgiven and used by God. And let's not forget to repent of the sin if we haven't already.
