“…But God knows my heart.”

The way I share Jesus is pretty basic: I talk with people. They ask what I’m doing. My answer is nearly always Christianity-related… ’cause that is what I’m doing. Sometimes they have hangups about religion, in which case I change the subject. But far more often they’ll talk about it. Frequently it turns out they’re Christian.

But there are Christians, and there are Christians. Some of ’em are devout. Some of ’em only think they’re Christian. Most often they’re just irreligious: They don’t pray. Don’t go to church. Never read their bibles; wouldn’t know were to begin. (Somehow they found out the bible doesn’t have to be started at the beginning—and ever since, they’ve used this as an excuse for why they never started. Sounds like the options simply stymie them. Maybe we’d better stop telling people they don’t have to start at Genesis, and tell ’em they totally do. But I digress.)

One of my shortcuts for finding out how religious they are, or aren’t: I ask where they go to church. And even though they should totally go, and know they should totally go, a lot of ’em just don’t. “Oh, I went to [big local church] all the time. I admit I don’t now; not as often as I ought to.” Seldom do they ever try to give the rubbish argument Christians don’t need to go. They kinda know that’s heresy.

But recently I bumped into someone who gave this excuse for skipping church.

ME. “So you’ve not gone recently?”

SHE. “No, I admit it’s been a while. But it’s okay; it’s a relationship, not a religion. And God knows my heart.”

It’s far from the first time I’ve heard the “But God knows my heart” argument. It’s really popular in the Bible Belt. “Yeah, I fully admit I [insert heinous sin] on the regular. But God knows my heart.”

Yes, God knows we have good intentions! Buried in us somewhere, deep down… ’cause they’re clearly not visible for anybody to see, or even deduce. But they’re in there, and that counts for something, right?

Yeah, you just keep telling yourself that. It’s how people eventually find themselves in this predicament:

Matthew 7.21-23 KWL

21 “Not everyone who calls me, ‘Master, master!’ will enter the heavenly kingdom.

Just the one who does my heavenly Father’s will.

22 At that time, many will tell me, ‘Master, master! Didn’t we prophesy in your name?

Didn’t we throw out demons in your name? Didn’t we do many powerful things in your name?’

23 And I’ll explain to them, ‘I never knew you.

Get away from me, all you Law-breakers.’

Except it’s even worse than Jesus describes it.

Yeah, worse. Read it again. Jesus is chiding people who prophesy in his name, throw out demons, do miracles. In other words, they do stuff. They minister to others—or try to. Problem is they’re “Law-breakers”—they don’t do what Jesus tells us to when it comes to loving God and our neighbors. They presume they have a relationship ’cause they’re ministers. They don’t, ’cause they’re not at all religious about their relationship.

Now these folks who figure God knows their hearts? Not even ministers. They don’t do miracles. Might not even believe miracles happen any more, or imagine God only grants such power to the super-devout, which they’re not. They got any evidence of any relationship with Jesus at all? Super nope.

God knows your heart? Yes indeed he does. And he knows it’s full of crap. Same as most of the Christians around you. You’re not really fooling anyone.

The wicked, deceitful human heart.

HEART hɑrt noun. Hollow muscular organ which pumps blood through the circulatory system.

2. [in popular culture] Center of a person’s thoughts and emotions; one’s mood, feeling, enthusiasm, mood, or courage.

3. [in popular Christian culture] Center of a person’s lifeforce; one’s innermost being; the true self, particularly one’s true thoughts and feelings.

4. A conventional heart shape, as found on a deck of cards.

[Hearted 'hɑrt.ɛd adjective.]

Jeremiah 17.9-10 KWL

9 “The heart is more twisted than everything.

It’s human. Who knows it?

10 I, the LORD, examine the heart and test the kidneys,

to give men according to their ways, the fruit of their deeds.”

The ancients didn’t know much about anatomy. So all the stuff we recognize are part of brain activity, the ancients believed were the function of other parts of the body. The heart, they imagined, did our thinking. The kidneys did the feeling.

Seriously. And why not? When we get excited, our hearts beat faster. When we’re sad or mournful, we feel it in the chest, and not so much the head. They saw a connection between mental activity and the heart. So they deduced it was the cardiac muscle behind our thoughts and feelings… not our thoughts and feelings behind our heart’s behavior. Yep, got it backwards.

What’d they imagine our brains did? Well, they didn’t. Seriously: The word “brain” isn’t in the bible. Y’might find it in various bible translations, but that’s because the translators know what the brain actually does, and decided to swap it for lev or kardía where appropriate. But in the scriptures, when we come across mental activity, the authors kept referring to one’s heart.

• The thoughts Ge 6.5 or imagination Ge 8.21 of one’s heart: Of one’s mind, really.
• Saying in one’s heart Ge 11.17, 24.45, Dt 9.4, 18.21 is saying to oneself, in one’s head, or at least privately.
• One’s heart failed or fainted or was discouraged Ge 42.28, 45.26, Nu 32.7, Dt 1.28 means they lost their nerve.
• One’s heart was hardened Ex 4.21, 7.13, Dt 2.30 means one’s mind is closed.
• One’s heart was stirred Ex 35.21, 36.2 is what we’d call a brainstorm.

We still do this in our culture. When we remember, we “search our hearts.” When we rethink things, we “have a change of heart.” When we make up our minds, we “determine in our hearts.” And so forth.

Medical science didn’t realize the brain’s importance till Hippocrates in the fourth century BC, and Galen of Pergamon in our second century. For the longest time, more folks were familiar with Aristotle, who claimed the brain’s job is to cool down our blood. Considering all the bible’s talk about thinking and saying with our hearts, most people up until the Renaissance assumed the heart literally did as the bible describes.

But as I’ve said before, the bible’s not a science textbook. When its authors wrote about other subjects than God, they repeated what their culture had told them. They’d always been taught so, and God saw no reason to correct them: “No, guys, you think with your brains, not your hearts.” He had bigger fish to fry. He even used their terminology: He stated he thought in his heart. Ho 11.8 He was trying to relate to humanity, and it wasn’t the occasion for a biology lesson.

So if you’re worried about the scientific inaccuracy of the scriptures, don’t. Unlike young-earth creationists, we aren’t making anti-scientific claims about human biology based on our overly-literal interpretations of the scriptures. We’re simply reading the bible so we can understand God better. To a lesser degree, we’re also trying to understand the sin-damaged human mind better, and if the bible’s authors persisted in using “heart” to mean “mind”… well, let’s adapt.
