“No distrust makes him waver concerning the promise of God.” (Romans 4: 20)
Instead, Abram “grows strong in his faith as he gives glory to God.” (Romans 4: 20)
Giving God the glory is the method through which Abram becomes “fully convinced” and unwavering in his belief in God’s promise to make him “the father of many nations.” (Romans 4: 18)
Both Abram and Sarai laugh as each hears God’s pronouncement that Sarai will bear Abram a son. Abram falls on his face and laughs when God tells him. (Genesis 17: 17) whereas Sarai laughs from within the tent as she hears the three angels announce to her husband that she is to be with child.(Genesis 18: 12)
The Lord challenges Abram, saying, “Is anything too hard for the Lord?” (Genesis 18: 14)
Sarai denies her laughter, but God reminds her — “No, but you did laugh.” (Genesis 18: 15)
Abram and Sarai change names at God’s command. Abraham circumcises himself at ninety-nine years of age. Sarah bears a son at ninety-one years of age. Through these two people, the new covenant begins. (Genesis 17: 21)
First, a scoffing laughter; then an unwavering belief.
