Revelation 3:20

John 14:21-23 NIV
Whoever has my commands and keeps them is the one who loves me. The one who loves me will be loved by my Father, and I too will love them and show myself to them.” Then Judas (not Judas Iscariot) said, “But, Lord, why do you intend to show yourself to us and not to the world?” Jesus replied, “Anyone who loves me will obey my teaching. My Father will love them, and we will come to them and make our home with them.

Luke 12:36-37 NIV
like servants waiting for their master to return from a wedding banquet, so that when he comes and knocks they can immediately open the door for him. It will be good for those servants whose master finds them watching when he comes. Truly I tell you, he will dress himself to serve, will have them recline at the table and will come and wait on them.

Matthew 24:33 NIV
Even so, when you see all these things, you know that it is near, right at the door.

Revelation 19:9 NIV
Then the angel said to me, “Write this: Blessed are those who are invited to the wedding supper of the Lamb!” And he added, “These are the true words of God.”

Song of Solomon 5:2-4 NIV
I slept but my heart was awake. Listen! My beloved is knocking: “Open to me, my sister, my darling, my dove, my flawless one. My head is drenched with dew, my hair with the dampness of the night.” I have taken off my robe— must I put it on again? I have washed my feet— must I soil them again? My beloved thrust his hand through the latch-opening; my heart began to pound for him.
