Jn 1:12, Lk 12:36, Rev 19:9
Jesus reveals that he is the Christ and is knocking on the door of people's hearts. (Revelation 3:20)
Revelation 3:20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
When we accept in our hearts that Jesus is the Christ, we become children of God. (John 1:12, 1 John 5:1)
John 1:12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
1 John 5:1 Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.
If we open our hearts and believe in Jesus as the Christ, we will participate in the wedding feast of the Lamb of God. (Luke 12:36, Revelation 19:9)
Luke 12:36 And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately.
Revelation 19:9 And he saith unto me, Write, Blessed are they which are called unto the marriage supper of the Lamb. And he saith unto me, These are the true sayings of God.
