Does “only God know the heart”? Or are there cases when we do too?

By Elizabeth Prata

Peoples’ responses to calling out a false teacher often (depressingly often) involves a statement such as this:

“You don’t know their heart!”

God is sovereign. God knows the heart. But there are specific times that we do too.

If a teacher’s doctrine has been proven false by comparing it with the Bible, then we DO know their heart! The Bible tells us this. Only God knows the hearts of the people, but if their teaching is not of the Lord, then the God who sees hearts has exposed those hearts to us by the verses of His word!

Their hearts are full of deceit. Colossians 2:8
Their hearts are filled with their own appetites. Romans 16:17-18
For out of the abundance of the heart the mouth speaks. Matthew 12:34
Their hearts are disguised with light. 2 Corinthians 11:13-15
Their hearts are full of greed. 2 Peter 2:3
Their hearts are ravenous. Matthew 7:15.
Their hearts are inwardly full of sensuality. Jude 1:4
Their hearts are full of secrets, such as destructive heresies. 2 Peter 2:1
Their hearts are full of intent to exploit. 2 Peter 2:3
Their hearts are full of fleshly passions. 2 Timothy 4:3
Their hearts are puffed up with conceit. 1 Timothy 6:4
Their heart understands nothing. 1 Timothy 6:4
Their hearts are cunning and crafty. Ephesians 4:14
Their hearts serve the creature. Romans 1:25
Their hearts are slaves of corruption. 2 Peter 2:19.
Their hearts deny the Master who bought them. 2 Peter 2:1
Their hearts prophesy lies. Jeremiah 23:26

People undiscerningly reject discernment and accept false teachings, even after confirmation by Bible verse, by thinking that a person can utter blasphemies but still have “a good heart”. No. Do we think that a person can utter falsities or even blasphemies from a pure heart? No, of course not. Out of the heart the mouth speaks.

God does know the heart, that’s true, but He has shown us the heart of the false teacher in His word. He taught us this in His word for the purpose of being mature, discerning, and so we can learn for ourselves in truth and also teach the younger to be edified and strong.
