In Revelation 3:20, Jesus stands at the door and knocks, not with force or anger, but with patience and longing. The word 'behold' is a personal invitation to pay attention to what He is doing. His knock is not loud or aggressive. It is a gentle whisper, a quiet nudge, a still small voice. What matters most is not simply hearing that knock, but how we respond to it. History has been shaped not by the most talented or famous, but by ordinary people who said yes when God called. One open door, one act of simple obedience, can set off a chain of events that changes the world. The question is not whether God is knocking. The question is whether we will open the door.
