1. Genesis 21:1-7: The Lord fulfills His promise to Sarah and she gives birth to Isaac in her old age.
2. Genesis 21:8-13: Sarah sees Ishmael, the son of Hagar, mocking Isaac, and she tells Abraham to cast out Hagar and Ishmael.
3. Genesis 21:14-21: Abraham provides Hagar and Ishmael with some supplies and sends them away into the wilderness.
4. Genesis 21:22-34: Abimelech and his commander visit Abraham, and they make a covenant concerning a well of water.

My applications:

1. Just as the Lord fulfilled His promise to Sarah, I should trust in God’s timing and promises in my own life, even when circumstances seem impossible.
2. Seeing Ishmael mocking Isaac, I am reminded to treat others with kindness and avoid mocking or belittling anyone, as it can lead to hurt feelings and conflicts.
3. Abraham’s willingness to provide for Hagar and Ishmael when they were cast out teaches me the importance of showing compassion and extending help to those in need.
4. The covenant made between Abraham and Abimelech highlights the significance of keeping my word and maintaining peaceful relationships with others.
