So we should baptise infants of believers because they are included in the covenant? Well why was Ishmael circumcised when he was not included in the covenant?
Gen 17:20, 21 "And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year."
