God is always reliable, and faithful to His promises. Sarah became pregnant, and gave birth to a son, Isaac. Abraham was 100 years old, and he circumcised his son eight days after he was born. When God gives us the mercies we began to despair of, we should remember our sinful distrust of His power and promise. Answered prayers might be delayed, but God never forgets His promises to His people. As to Ishmael, he began to oppress and mock the son of the covenant, and for that reason, he was removed from the presence of Isaac, the son of the covenant, lest he corrupt the manners or take the rights from Isaac. If Hagar and Ishmael had behaved well in Abraham's family, they might have continued there; but they were justly punished. Nevertheless, God made a promise to bless Ishmael being a child of Abraham. And the two went and lived in the wilderness of Paran, part of Egypt. It is wise to connect ourselves with those who are blessed by God, as Abimelech did with Abraham. But we must show kindness who had been kind to us. God bless.
