The heart is deceitful above all things, and desperately wicked; who can know it? (Jeremiah 17:9 (NKJV))

Do you know what’s in your heart? Probably not. As we see from the verse in Jeremiah, our hearts are deceitful. That means you can think your heart is fine even when it isn’t. Yet, the contents of your heart can be revealed by your words.

As Jesus said,

A good man out of the good treasure of his heart brings forth good; and an evil man out of the evil treasure of his heart brings forth evil. For out of the abundance of the heart his mouth speaks. (Luke 6:45 (NKJV))

That may seem harsh. But it’s true. Whatever’s in your heart – good or evil – will come out.

The contents of your heart can be revealed at the most inopportune moments – like when you stub your toe on the corner of the coffee table or when someone cuts you off in traffic. The curse words that come out of your mouth may surprise you. But the circumstances didn’t cause them. They were the result of what was already in your heart.

The Bible has many examples of people who were unaware of the contents of their hearts. In one, Jesus revealed what was in the scribes and Pharisees’ hearts.

Remember how Jesus healed the man with the withered hand? When Jesus healed him, “his hand was restored as whole as the other” (Luke 6:10 (NKJV)).

Wouldn’t that have been amazing to see – to watch with your own eyes as a man’s withered hand was regenerated into wholeness? It was a miracle.

But when the scribes and the Pharisees saw it, the Bible says that “they were filled with rage” (Luke 6:11 (NKJV)). A man’s hand had been fully restored, and they were moved to a madness that was expressed in anger. Why? Their hearts were wrong. They were laser-focused on a rule – a man-made interpretation of God’s law.

God had commanded, “Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the Lord your God. In it you shall do no work . . . .” (Exodus 20:8–10a (NKJV)). Over time, they twisted God’s law to mean that supernaturally healing someone constituted work.

Their hearts were so focused on their interpretation that they missed the miraculous. In fact, they had watched Jesus closely to see if He would heal the man. They wanted to find something they could use to bring charges against Him (Luke 6:7).

So, how do you know what’s in your heart? Ask God to show you. Pray: “Search me, O God, and know my heart; try me, and know my anxieties; and see if there is any wicked way in me, and lead me in the way everlasting” (Psalm 139:23–24 (NKJV)).

When God reveals something in your heart that shouldn’t be there, repent. Admit that you’re wrong and that God is right. Ask God for forgiveness. And then walk by faith with God in the freedom that only He can give.
