Love God With All Your Mind: Thinking as an Act of Worship

When Moses gave Israel the great command, he said to love God “with all your heart and with all your soul and with all your might” (Deuteronomy 6:5). When Jesus quoted it, He added a word: “and with all your mind” (Mark 12:30).

That’s worth noticing. Jesus didn’t think loving God was only a matter of feeling or devotion. He expected His followers to think.

This is part three of a series on the Greatest Commandment. We’ve looked at the heart and the soul. Now the mind.

Two ditches

There are two ways to get this wrong, and churches tend to fall into one or the other.

The first ditch is a faith that doesn’t think. “Don’t ask questions, just believe.” It sounds humble, but it leaves a man with a faith that can’t survive a hard conversation, a college classroom, or a funeral. When the hard question comes, and it will, he has nothing to stand on.

The second ditch is a faith that only thinks. A man who can argue theology all night but whose knowledge never reaches his hands or his heart. Paul warned about that too: “knowledge puffs up, but love builds up” (1 Corinthians 8:1).

Loving God with your mind runs between those ditches. It’s thinking hard because you love Him, and thinking in a way that makes you love Him more.

John Stott put it simply in Your Mind Matters: “Knowledge is indispensable to Christian life and service.” You can’t love Someone you don’t know. And you can’t know God well without using the mind He gave you.

A mind that needs renewing

Here’s the catch. Our minds aren’t neutral. They’ve been shaped by a world that doesn’t know God, and by our own sin, which is very good at producing reasons for what we already want.

That’s why Paul says: “Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect” (Romans 12:2).

Notice the order. A renewed mind comes before a discerning life. What you think about shapes what you love, and what you love shapes what you do.

Every man knows this from the other direction. Temptation almost never starts with the action. It starts with a thought you let sit there, then entertain, then rehearse. By the time you act, you’ve already made the decision a dozen times in your head. That’s why Paul describes the fight as a battle for thoughts: “We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ” (2 Corinthians 10:5).

The mind at peace

The good news is that a mind fixed on God isn’t just safer. It’s more at peace. “You keep him in perfect peace whose mind is stayed on you, because he trusts in you” (Isaiah 26:3).

Anxiety is often a mind running loops on what might go wrong. Worship is a mind fixed on what is true about God. Paul gives us a filter for what to let into our heads:

“Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.” (Philippians 4:8)

That isn’t a call to only read Christian books. Plenty of true, honorable, excellent things are found in history, science, good fiction, and a well-written repair manual. All truth is God’s truth. The question is whether what you’re feeding your mind builds you up or drags you down.

Ten ways to love God with your mind

1. Read the Bible with a plan. Not random verses. Whole books, start to finish, so you see the story and the argument. A reading plan keeps you from living on your three favorite chapters.

2. Memorize Scripture. One verse a week. Write it on a card and keep it in your pocket or on your dashboard. A memorized verse is a weapon you carry into every temptation and every anxious night.

3. Meditate, don’t just read. The blessed man’s “delight is in the law of the LORD, and on his law he meditates day and night” (Psalm 1:2). Take one sentence and turn it over. Ask what it says about God, what it says about you, and what you should do.

4. Read one solid book a quarter. Pick a book by someone who’s thought longer and harder than you have. A classic like C. S. Lewis’s Mere Christianity, or something on a doctrine you’ve never understood. Read it with a pencil.

5. Learn the faith you profess. Work through a catechism or a statement of faith. Know why you believe the Trinity, the resurrection, and justification by faith. Peter says to always be ready to give a reason for your hope (1 Peter 3:15).

6. Ask your hard questions out loud. Don’t bury your doubts. Bring them to God and to a pastor or a brother you trust. Honest questions asked in faith are not the enemy of faith.

7. Audit your inputs for one week. Write down everything you watch, scroll, and listen to. Then hold it up to Philippians 4:8. You don’t have to quit everything. But you’ll probably find one thing to cut.

8. Catch the thought early. When a tempting or anxious thought shows up, name it and answer it with truth before it settles in. “That’s a lie. Here’s what’s true.” Taking thoughts captive is a skill, and it grows with practice.

9. Think while you work. Listen to a sermon, a good podcast, or the Bible on audio during your commute or in the shop. Turn the dead time into learning time.

10. Teach someone else. Nothing clarifies your thinking like having to explain it. Lead a short study, disciple a younger believer, or just explain to your kids what you read this morning.

Thinking toward love

The point of all this isn’t to become a scholar. It’s to know God better so you love Him more. Peter put the mind and the hope together: “preparing your minds for action, and being sober-minded, set your hope fully on the grace that will be brought to you at the revelation of Jesus Christ” (1 Peter 1:13).

A mind fixed on that grace will stay steadier, fight temptation better, and worship deeper.

Pick one or two. If you’re in Agōn, one of these might be your Mind discipline this season.
