K.C. Moser in his book, Attributes of God, has a chapter on knowing God. He lists three ways of knowing God: (1) through creation, (2) through revelation, and (3) through Christian experience.
Knowledge of God through Creation. Knowledge of God through creation is discussed in several passages:
The heavens declare the glory of God, and the sky above proclaims his handiwork. (Psalm 19:1, ESV)
For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. (Romans 1:19-20, ESV)
When we consider creation, we can learn something about God. We still need revelation in order to come to a saving knowledge of God, but there is something for us to learn from creation.
Knowledge of God through Revelation. Knowledge of God through revelation is critical. Without scripture, we would not know of our spiritual condition or God’s solution.
All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work. (2 Timothy 3:16-17, ESV)
Knowledge of God through Christian Experience. Our knowledge from experience must be based on our knowledge from revelation. Yet, we must also see that knowledge of Bible content must be put into practice. This daily living adds a deeper dimension to our knowledge of God. One could know all the facts about Jesus’ sacrifice for us, but Paul also writes “…and hope does not disappoint, because the love of God has been poured out within our hearts through the Holy Spirit who was given to us” (Romans 5:5, NASB). This speaks of a love that the Christian comes to experience and feel, because of what Christ has done. The love of God and neighbors are concepts to be learned (Matthew 22:35-40) but also experienced in our service to God and ministry to others.
May we all come to know God from creation, revelation, and experience. When our knowledge of God from creation and revelation goes on to the knowledge of experience, it has moved from facts about faith to a life of faith. That is what Christian maturity is about. How do you know God?
