God’s Promise to Abraham and Sarah: Isaac Is Born — High School Sunday School Lesson

Free High School Sunday school lesson on Genesis 18:1–15 and 21:1–7. This reviewed eight-page guide with passage background, timed plan, source study, claim check, key, and family page supplies a volunteer ready-to-use, verse-based lesson. The Lord promises Sarah a son at the appointed time; she laughs in surprise; the Lord tells the truth; and Isaac is born as God spoke. The guide treats this as a particular promise to Abraham and Sarah, not a guarantee of pregnancy for every family.

Memory verse: “Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.” Genesis 18:14, KJV. The guides care for varied family stories, distinguish Isaac from the Savior, and connect to Christ’s death and resurrection from later Scripture. Read both passages in your preferred translation.
