“‘Behold, I stand at the door and knock; if anyone hears My voice and opens the door, I will come in to him and will dine with him, and he with Me.’” (Revelation 3:20, NAS)
As I read this verse, I was thinking that it is not enough to have God standing at the door and knocking. When He is speaking and I hear His voice, it is still up to me to take the action of opening the door to let Him in. Without the corresponding action as a result of hearing the Word, nothing happens.
If you hear His voice, open the door!
