Each of the prior categories is an entire field of study and the subject of thousands of books. Yet the existence of God is demonstrated most profoundly, for most people, in personal experience. It may be impossible to “prove” to others that you’re happy, for instance, but that doesn’t change the fact that you are. That’s not to say internal perspective outweighs objective truth, but complex truths are often powerfully supported by individual experiences. Changed lives, reformed attitudes, and answers to prayer are all part of our personal perception that God exists.

A personal sense of truth is the most compelling way we know God exists, and it’s God’s intent for all people to experience that sense. God came to earth personally, as a human being (2 Corinthians 4:6), so we could have a personal relationship with Him (John 14:6). Those who sincerely seek God will find Him (Matthew 7:7–8), resulting in the abiding presence of the Holy Spirit (John 14:26–27).
