How Can I Know That God Exists?

We know through various kinds of revelation that God exists.  God is revealed through creation, the Bible, through personal relationships with people.  A  person asking, "How can I know that God exists?" is probably looking for God.

I would encourage such a person not to worry about doubts and to trust God to reveal more and more of himself in these 3 ways.

All of nature reveals the existence of God.  David wrote in Psalm 19:1  "The heavens declare the glory of God; the skies proclaim the work of His hands."  Wherever there is a design, there must be a designer.  Theologians call this "general" revelation, because it is available to all people at all times in all places.  Besides the external source of "general" revelation, which is the conscience.  (Romans 2:14-18).

Through our moral sense of right, Christ is the Son of God and trusting him and him alone to deliver us from sin.  Jesus came to reveal the person and nature of God.  We can know that God exists through experiencing a personal relationship and fellowship with Jesus.   (John 14:9-11)  Recommended resource:  The God Who Is There  by Francis A.
