Rev 3:20 Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me.
John 10:9-16 I am the door. If anyone enters by Me, he will be saved, and will go in and out and find pasture. 10 The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have it more abundantly. 11 I am the good shepherd. The good shepherd gives His life for the sheep. 12 But a hireling, he who is not the shepherd, one who does not own the sheep, sees the wolf coming and leaves the sheep and flees; and the wolf catches the sheep and scatters them. 13 The hireling flees because he is a hireling and does not care about the sheep. 14 I am the good shepherd; I know My sheep, and am known by My own. 15 As the Father knows Me, even so I know the Father; and I lay down My life for the sheep. 16 And other sheep I have which are not of this fold; them also I must bring, and they will hear My voice; and there will be one flock and one shepherd.
