Some People grow out of stuttering...Some do well with Therapy...Some seek & get help from God/Jesus by attending regular weekly healing and deliverance services at their Apostolic Bible Believing full gospel Church...Moses stuttered..That fact was omitted from The Charlston Heston Ten Commandments Movie... But it is a true fact...The Bible never said Moses was fully delivered... but his speech and his communication skills likely got better and better gradually over the years..God/Jesus/Holy Spirit is a way maker and Miracle Worker.. Seek His help like you do everyone else's..even greater.
