Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom. Matthew 16:28
Most Christians do not realize that Jesus’ promise of his second coming did not apply to our generation or to a future generation, but only to the generation of his time. Also, Jesus said in Rev 3:11: “Behold I come quickly…“
Those poor people of early Christianity! They thought the texts got written for them, yet Jesus never fulfilled his promise.
Two thousand years have rolled by and yet many “true” believers still await his “quick” return. As any school child knows, anyone who does not keep promises does not deserve our trust, much less our admiration.
Furthermore, to believe in a second coming and the end of the world gives no reason to feel concerned about the long-term future of Earth. Why should we care about the environment, wars, or suffering if we believe that the world will come to an end soon and that everything will get taken care of in heaven?
