There are different kinds of doors. Some are so light that a kick is enough to get them down. However, some cannot be easily removed, broken, or replaced because of their high quality fabricated material. It will take another super machine to break through these solid doors; otherwise, it might be best to slip through if there are openings beneath them. I believe no solid doors will carelessly permit any tiny spaces underneath for safety purposes such as against fire. This is why knocking seems the appropriate way by which the owner of the door will let you in. Knocking means humility to get through. You violate the rules of life when you use a bulldozer to break down the door that won’t open at your command. And you might finish up in a prison for that crime. However, knocking depicts your humbleness and the willingness to corporate with the person behind that door. You are knocking because you know there is something by far best behind that door that will alter the course of your life forever, positively.
So, are you ready to knock?
