This may help you to understand. Most people do not realise that the Bible message is to three groups of people.
The first group are 144,000 humans who will be taken from the earth to rule over the earth with Christ Jesus as their King. This is the heavenly kingdom that we are told to search for, at Matthew 6:33. There are only a few of these left remaining on earth and they are very old. (Please reason onRevelation 14:1,3; 5:10)
The second group are people who are given the opportunity to live forever on a paradise earth. This is only for people who learn the truth about the Bible and by accurate knowledge dedicate their lives to serve the one true God, Jehovah and his King-Son Jesus Christ. (John 17:3; Matthew 5:5)
The final group are people on the earth who do not love truth or God’s Word the Bible, or who seek to serve God their own way and not how God requires, or who seek independence from God and look to human governments and false religion for guidance.
