Jesus warns that not all people who think that they will go to heaven will go there.

Luke 13:22-30; Matthew 7:13-14,21-23

22 Jesus continued traveling, along with his disciples, through various towns and villages on the way to Jerusalem. As they went, he was teaching the people. 23 Someone asked him, “Lord, will there be only a few people who are saved {whom God saves}?” He replied to them, “There will not be many, because the way to heaven [MET] is like a narrow door. 24 Therefore, try hard to enter that narrow doorway, because I tell you that many people will try to enter heaven by some other way, but they will not be able to get in. 25 God is like the owner of a house. Some day he will lock his door. Then some of you will begin to stand outside that door and knock. You will say, ‘Lord, open the door for us!’ But he will reply, ‘No, I will not open it, because I do not know you, and I do not know where you are from!’ 26 Then you will say, ‘◄You must have forgotten!/Surely you know us, because► [RHQ] we (exc) ate meals with you (sg), and you taught people in the streets of our towns’! 27 But he will say, ‘I tell you again, I do not know you, and I do not know where you are from. You are wicked people! Get away from here!’” 28 Then Jesus continued, saying, “From where God will send you, you will see Abraham and Isaac and Jacob in the distance. All the prophets who lived long ago will also be there, in the kingdom where God is ruling. But you will be outside, crying and grinding your teeth because you will have severe pain! 29 Furthermore, many non-Jewish people will be inside. There will be ones who have come from lands to the north, east, south, and west. They will be feasting in ◄that place where God is ruling/God’s kingdom►. 30 Think about this: Some people whom others do not consider important now, God will make them very important then, and some people whom others consider very important now, God will make to be not important then.”
