Everyone knows what it means! Come on! Give me a break! I had an old car and the engine used to knock! Not very pretty! Jesus said knock and it shall be opened unto you! We know what he meant but our point of reference could be wrong! The Greek root word used for the English word knock used in this passage of scripture means to overthrow from captivity! So you are knocking on the door to escape from your captivity of sin! When you knock and Jesus opens the door you are not inviting him in for a cup of tea! You are going through a fire escape leaving a burning building named Hell! Jesus is inviting you into His House and you are exiting Hell! Your house will not stand! Remember the four men that carried the paralyzed man to Jesus on a stretcher? The crowd was so great around the house he was visiting that they tore the roof apart to get to Jesus! They wanted the paralyzed man to escape his physical captivity! Notice Jesus was first concerned with his soul! We are exiting our troubles and entering into His Kingdom with protection from Hell and death! How do we as believers knock on the door? We attend church regularly! We tithe and make offerings to God through our local church! We read and study our Bible daily and pray often! Can Jesus hear your knock? Thankyou. James and Hamsa Sasse. GodWhoisGod.com
