Genesis Chapter 21 "The Birth of Isaac"

Recap: Isaac is born because God delivers on his promises (pun intended). Sarah still harbers resentment towards Hagar and tells Abraham to cast her out with Ishmael. Although, this displeases Abraham, he obeys with the command of God. God promised to make great nations out of both boys. When there was no water left, Hagar was in desperation and could not bear to see her child suffer and left him alone to die. God shows up in the time of need when it appears faith has been lost and shows Sarah where a well of water is located. Time passes and Ishmael becomes an archer. Abraham makes a covenant with Abimelech.

Takeaway:
1. Do not succumb to desperation and keep your faith as the father will provide
2. Resentment can cause a holy person to perform harmful acts
