I heard this story on Christian television awhile ago. Suppose you lived in a middle class neighborhood with your family and someone you didn’t know came to your door and asked to live with you. Would you let them in? Because you have no idea who the person is and because you would want to protect your family, you would almost certainly close the door on them. Similarly, God only lets people into heaven whom He knows. Heaven is a perfect place and if God let people in who have not built a relationship with Him, then heaven would be anything but perfect.
But what does it mean to know God? All of us have sinned according to the Bible and all of us deserve hell. It is only because of what Jesus did on the cross to take away our sin that any of us have a hope of heaven if we believe in Jesus Christ as Savior and Lord. Jesus made it very clear when He said, “No person comes to the Father(God) except through me.” There is only one door into heaven, not numerous doors as the New Age belief system attempts to get us to believe. Jesus is that door, and not just a mental assent of Him as Savior, but as the Lord of our life to whom we look for direction on a regular basis.
