God has reaffirmed the covenant with Abram and changed his name to Abraham. Now he establishes a sign of the covenant with the practise of circumcision to remind him and future generations that God does not need our help to fulfill what He has said He will do. He then gives Sarai the new name of Sarah. The thought of becoming a father at the age of 100 and with his wife Sarah at the age of 90 brings laughter to Abraham as he thinks of the complete impossibility of such an event.
Abraham was circumcised at 99 years old. Ever wonder who performed that ceremony on Abraham? You will need to listen to discover who it was.
