How Do We Know?

How Do We Know?

Q 3: How may we know there is a God?
A: The light of nature in man and the works of God plainly declare there is a God; but His Word and Spirit only do it fully and effectually for the salvation of sinners.

“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 complete, equipped for every good work.”

(2 Timothy 3:16–17 ESV)

“Show me proof that God exists and I will believe!”  This familiar expression has been uttered from the lips of unbelievers on countless occasions.  They argue that because they see no evidence for God, he must not exist.  But as we have already seen, there is plenty of evidence for the existence of God.  In fact, “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)

Why would anyone who can see the world around them not simply believe in God?  It only seems logical that they would believe what they can clearly see.  But in this case, the idea of “seeing is believing” is simply not true.  In fact, the opposite is the case: “believing is seeing.”  For a person to believe, they first have to have their eyes opened to the truth.  They have to believe! Then they can see the truth about the glory and majesty of God.

Although everyone “ought” to believe there is a God, and the light of nature in man and God’s creation declare there is, until the Word of God and the Spirit of God work on a man’s heart, that man will not believe.  It requires the truth of God’s Word and the work of the Holy Spirit to cause a man to believe.  Only those two working together can cause a man to believe “fully and effectually” unto salvation.  

The Bible is our starting point for this journey.  It is “breathed-out” or “expired” by God. The Holy Spirit spoke into the lives of men and inspired particular writings that have been handed down through the ages.  These writings, as they are applied by the Holy Spirit, are what remove the blinders from the eyes of God’s children.  


Read 1 Cor 2:6-16 and answer the following questions:

  • What is the “secret and hidden wisdom of God” discussed by the Apostle Paul?
  • Verse 10 talks about the Spirit revealing these things.  What has the Spirit revealed?
  • Why would the natural person not accept the things of the Spirit?
  • Romans 12:2 says that we are to be “transformed by the renewal of” the mind.  What are some ways that we can renew our minds with God’s Word?
