That may seem like a ridiculous question but the Bible actually tells us that God does not know everyone. In the book of Matthew, Jesus tells us that on judgment day there are people who are going to be turned away from heaven because God does not know who they are.
Matthew 7:21-23 tells us: “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’”
Those who practice lawlessness will be turned away from heaven. To practice lawlessness is to live life continually doing things you know are wrong. Many people throughout America falsely believe that as long as they believe in God, they will go to heaven. They believe that they can live their life anyway they choose. After all, God is a loving God who always forgives our sin, right? It sounds good, but it’s not what Jesus said. Jesus made it very clear that you have to do the will of the Father.
