What is the difference between knowing about God and knowing God personally?

You can memorize the books of the Bible, understand the doctrine of the Trinity, and win every theological trivia contest at church, and still not actually know God. This might sound strange, but Scripture draws a sharp and important line between knowing facts about God and actually knowing Him, a distinction with eternal consequences.

Jesus warns of people who will say, “Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?” only to hear Him respond, “I never knew you; depart from me” (Matthew 7:22-23). Impressive religious activity and accurate knowledge are not the same thing as an actual relationship with God.

Knowing about God is essential and good, it involves learning sound doctrine, studying Scripture, understanding God’s attributes, and being able to articulate truth accurately. Paul commends Timothy for knowing “the sacred writings” from childhood (2 Timothy 3:15), and the church is repeatedly commanded to grow in knowledge (2 Peter 3:18). This kind of knowledge matters; you cannot rightly love a God you have wrong or fuzzy ideas about.

But James issues a sobering warning: “You believe that God is one; you do well. Even the demons believe, and shudder!” (James 2:19). Demons possess flawless theological knowledge, they know exactly who God is, without a shred of doubt, yet they are the furthest thing from being in relationship with Him. Correct information alone, however extensive, is not saving faith.

Knowing God personally is relational, trust, love, communion, and obedience flowing from an actual encounter with Him, not merely facts stored in the mind. Jesus defines eternal life this way: “this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent” (John 17:3). This is knowledge in the biblical sense of intimate relationship, the same word used for the closest of human bonds (Genesis 4:1).

Paul, a man saturated in theological training before his conversion, describes his transformed priorities after meeting Christ: “I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord… that I may know him and the power of his resurrection” (Philippians 3:8-10). Notice this is not new information Paul lacked; it is a relationship he had not yet entered, even as a zealous, knowledgeable Pharisee.

Paul’s prayer for the Ephesian church models what mature faith looks like: he asks that God would give them “a spirit of wisdom and of revelation in the knowledge of him, having the eyes of your hearts enlightened” (Ephesians 1:17-18). Notice that Paul prays for knowledge, but knowledge that reaches the heart, not merely the intellect, knowledge meant to be experienced and felt, not just recited.

Later in the same letter, Paul prays that believers would “know the love of Christ that surpasses knowledge” (Ephesians 3:19), a striking, almost paradoxical phrase. He is not contradicting himself; he is describing a knowing that goes beyond what facts alone can capture, an experiential grasp of being loved by Christ that changes a person from the inside, even though it can never be fully reduced to information.

Knowing about God and knowing God are not opposed to each other; rightly understood, the first serves the second. Sound doctrine gives shape and substance to the relationship, you cannot trust, love, or obey a God you have completely wrong ideas about. Growing in accurate knowledge of who God is deepens and enriches genuine relationship with Him (Colossians 1:9-10).

But knowledge alone, without trust and surrender, stalls at the doorway and never enters the relationship itself. This is the tragedy of religious knowledge divorced from personal faith: possessing the map without ever taking the journey, admiring the portrait without ever meeting the person it depicts.

It is worth asking honestly: is your Christianity primarily a set of facts you affirm, or a relationship you are actually living in, marked by prayer, trust, repentance, and love for Christ? Both matter, but only one of them saves. Salvation is not granted for correct answers on a theology exam; it is granted through actual faith in, and relationship with, Jesus Christ (Romans 10:9-10).

The good news is that this relationship is available to anyone, regardless of how much or little they currently know. Growing in knowledge of God is a lifelong pursuit, but knowing God personally begins the moment you turn to Christ in genuine trust, and from there, the two, knowledge and relationship, grow together for the rest of your life (2 Peter 3:18).
