This question is no doubt the most important question in the universe. If God exists and the Bible is true, then we are in trouble! If God does not exist and there is no purpose to life, nor is there life after death, then we are in trouble! So this appears to be the ultimate question with crucial consequences.

In order to follow this we must first understand the law of cause-and-effect (causality). This is the principle that for every effect (or event) there is a cause. This is the idea that it is impossible to have something happen without a cause. It is metaphysical principle called ex nihilo nihil fit (which is Latin for “Out of nothing comes nothing“). Causality is easily observed and identified. For example: leaves move because of wind, it snows because of temperature and moisture, rockets launch in the air because of burning fuel etc.
