Although the existence of God has been debated throughout the years, there are some very good arguments which have developed. The following are the most popular.
Cosmological Argument – Since the world exists and something cannot come from nothing, God must exist.
Teleological Argument – Since the world is ordered and logically arranged, there must be an intelligent organizer. There must be a master architect since the world evidences intelligence, purpose, and harmony. Ps 8:3-4; 19:1-4 testify that creation itself speaks of God. The idea that this kind of organization could happen by accident (as Evolution proclaims) is like a tornado ripping through a junkyard and assembling a Boeing 747.
Anthropological Argument – There are things within man (intellect, sensibility, will, conscience, and inherent belief in a creator) which could never have found their origin in some “blind force,” therefore God must exist. Man is not simply a physical being, but he is emotional and spiritual – this speaks of God.
Moral Argument – If man is only biological, why does he have a sense of right and wrong? It must be from God. Man is different from all the rest of creation in this way. Recognition of moral standards are found in every culture, yet could never be attributed to any sort of evolutionary process.
Ontological Argument – This one isn’t as strong as the others, but it basically suggests that since every culture (all men) have had an awareness of God, then God must have placed that idea in humanity. Therefore, He exists. Anselm (1033-1109) was the first proponent of this view.
How does this affect me? As a youth minister, I get these kinds of questions/challenges all the time. I’d say it’s actually one of the favorite topics, among our students. I enjoy these conversations because these arguments are pretty strong and they can lead into some great evangelism-type situations.
