Is Anything Too Hard for the LORD? Genesis 18:1-15 The LORD appears to Abraham and Sarah to reaffirm His Gospel promise. 1. Three strangers and Abraham’s generous hospitality. (Genesis 18:1-8) a. Behold the Gospel implications of hospitality. 2. The promise reaffirmed and Sarah’s scoffing unbelief. (Genesis 18:9-15) a. Beware of scoffing at God’s almighty Gospel promise. 3. Scoffing Sarah ultimately believes. (Hebrews 11:11-16) a. Barely believing believer, God forgives and helps our unbelief!
