1st. Causation- fact that we live in a cause & effect universe. It demands a 1st cause. Only God could explain the first cause.
2nd. Creation- fact that we live in a universe that is fine tuned with extreme order. Random chance is distructive to order. Nature is full of design which demands a Designer.
3rd. Conscience- fact that our universe has moral absolutes. Even if not obeyed, example of stealing, is wrong everywhere. Good & evil doesnt exist in a world void of God.
4th. Christ- fact is, there are evidences for Christ' existance, miracles, & resurrection. Just using standard witness & testimony, the evidence is overflowing. Not a scientific but a historical proven fact.
