I do not know where you come from

Jesus Christ came to the earth to fill the heaven with his people - After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, and crying out with a loud voice, Salvation belongs to our God who sits on the throne, and to the Lamb! - Revelation 7:9-10

So, as a follower of Jesus Christ, we should always work for heaven should be filled with great multitude that no one could number.

But a person asked the question with an idea that only small number of people including him would make it to the heaven, And the question is just against the will of God - And someone said to him, Lord, will those who are saved be few? - Luke 13:23a

Lords answer tells that how much he hate that question - And he said to them, Strive to enter through the narrow door. For many, I tell you, will seek to enter and will not be able. When once the master of the house has risen and shut the door, and you begin to stand outside and to knock at the door, saying, Lord, open to us, then he will answer you, I do not know where you come from. Then you will begin to say, We ate and drank in your presence, and you taught in our streets. But he will say, I tell you, I do not know where you come from. Depart from me, all you workers of evil! In that place there will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God but you yourselves cast out. And people will come from east and west, and from north and south, and recline at table in the kingdom of God. And behold, some are last who will be first, and some are first who will be last - Luke 13:23b-30
