What an interesting pairing of verses between the Old and New Testaments today! Abraham receives God's covenant, and the circumcision for him wasn't just for himself, but for anyone in his household. That included people who weren't blood relatives. The blessing God wanted to pour out on Abraham was broad enough to be shared. Of course, the blessing itself wasn't the whole point. It wasn't intended to be some badge of exclusion. In Jesus's day, it appears that the religious leaders were more focused on the fact that they were God's special people than the blessing they were made to pass along. Good thing Jesus came to set them straight!
