Genesis 15:6 And Abram believed the LORD, and the LORD counted him as righteous because of his faith.

After attempting to force a blessing by having Ishmael, God clearly told Abram that he and his wife were going have a child (Gen. 17:16). Abram was 100 years old and Sarai was 90 years old. Sarai was not present when God made this promise to the now Abraham, but she obviously was informed by Abraham on what God said because she accepted her new name of Sarah. In Genesis 18:10, a messenger of God confirmed God’s promise by telling Abraham that he and Sarah were going to have a child the following year. This time, Sarah was present, but she laughed in unbelief. Not only did she laugh, but she lied about laughing to Abraham and God.

Obviously, Sarah had a lot of doubt in her heart and it’s logically understandable. This woman has been attempting to have a child for at least 75 years and she has never heard of a woman giving birth in her 90’s. Sarah may have had doubt, but Abraham didn’t. From the beginning, Abraham believed God.

God set a hierarchy for the family. The husband is head of the wife (Eph. 5:23). Abraham, being the head of his household, believed God and although Sarah had doubt in her heart, his belief set in motion the promise of God manifesting in their lives. By Abraham’s faith, the Lord fulfilled His promise and blessed Abraham and Sarah with Isaac.

HUSBANDS, it’s important to get in the Word of God and build up your faith. The faith you have or don’t have will help or hurt your families. WIVES, it’s important that you properly submit to a man whose faith is fully in God and God alone.

Genesis 21:1 Now the Lord was gracious to Sarah as he had said, and the Lord did for Sarah what he had promised.
