The resurrection of Jesus Christ is one of those historic events theologians and Christian apologists have worked very hard to "prove." And rightly so. No less a biblical authority than the apostle Paul says the faith of all who follow Christ is "futile" if Christ has not been raised from the dead (1 Cor. 15:17). So it's not enough to believe Jesus is some kind of life force that fills all people, and it's certainly not acceptable to conjecture that God is going to rescue humanity apart from the risen Christ. Either Jesus is alive today and the Christian faith is true, or Jesus is still dead and the Christianity is a joke.
The good news is that there is enough historic evidence to reasonably believe the resurrection of Jesus Christ took place as the Bible describes. There's the proof of the empty tomb, the proof of hundreds of eyewitnesses, and the proof of transformed believers who sacrificed everything for what they knew to be true.
