With Jesus standing their knocking, where are you in relationship to your door? Does the door open easily and smoothly? Are you someone who is always inviting Jesus into your life. So when you here the knock you stop what you are doing, get still and invite Jesus in. Or is you door covered with overgrown vines and brush growing up around it because you haven't opened the door in a very long time. It has been so long since the door has been open that you aren't even sure you heard a knock. Jesus will not break down the door. He will not force a relationship.
