Guard Your Heart

I recently found the piece of paper that I was given at the last campus ministry large group service I attended before college graduation. On it is a single verse, a verse that I was told at the time was particularly for me:

Above all else, guard your heart, for everything you do flows from it” (Proverbs 4:23 (NIV)).

At the time, at 22, I was a bit thrown off by this verse. What did that mean? What was I doing to make it seem like my heart was too exposed? Ten years later I can say,

I didn’t know what I was supposed to be guarding. 

But, I wasn’t aware of how to read the Bible for that information at the time. The Bible seemed very removed from my everyday experience. Though I found parts of it interesting, I simply could not see how the Bible could speak much to my present day life.

Over the next six years, my life gradually falling apart, I tried everything else I could think of to guide me instead. The Bible eventually came back into my purview as almost a last resort, when I was exhausted from running into dead ends. Gradually, I had unwittingly done the opposite of “my verse” and let my heart be influenced by almost anything and everything else besides the Truth of the Bible. 

The heart can be manipulated when you don’t know its worth.

The worth of anything can seem different depending on who you ask. But God, the Creator of all things that have worth, determines the true value of our hearts. To uncover why it is so important to guard our hearts, I first needed to understand, from God our Creator’s perspective, what the heart really is and what it is worth.

In looking at the heart closer by how God hardened Pharaoh’s heart in Exodus and how Jesus quoted Isaiah 29 in Matthew 15, we can discover that in the Bible, the heart of a person is referring to the sum of their intellect, will, and emotions. It is like our steering wheel; wherever our heart goes, we will follow. The human will and emotions will surely wander into dangerous territory if they are not rooted. Jesus quoted Isaiah 29:13 which says, “their hearts are far from me. …” in describing the Pharisees, who had staked their lives on being the opposite! We must guard our hearts from getting far away from God, because where the heart goes, we will go with it. 

The heart is so significant that it is what the Lord judges us by. 

Every individual’s heart is precious and valuable. God made us this way. As our Creator, He knows where to look to see our true selves. 

But the Lord said to Samuel, ‘Do not look on his appearance or on the height of his stature, because I have rejected him. For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart’” (1 Samuel 16:7). 

When our hearts are aligned with the Lord’s character–His love, peace, and grace, we are no longer so prone to having our hearts manipulated. Knowing God’s character is knowing the Truth, which sets us free (John 8:32). 

If your heart is not planted in Truth, you will believe lies. 

We see this in Matthew 25:24-30 in the parable of the talents (sum of money). While this is a familiar and oft-taught passage, I had never caught the fatal error of the heart that the servant made before:

He also who had received the one talent came forward, saying, ‘Master, I knew you to be a hard man, reaping where you did not sow and gathering where you scattered no seed, so I was afraid, and I went and hid your talent in the ground …’ . ‘You wicked and slothful servant! You knew that I reap where I have not sown and gather where I scattered no seed? … . …cast the worthless servant into the outer darkness….’” 

Did you catch it too? The error of the servant was not so much what he did with the talent as it was his misperception of his Master’s true character! In this parable, the Master represents the Lord. It was the servant’s false assumption about who his Master was that determined both his fear and his resulting behavior. His heart had come up with a lie about the character of his Master, and he had believed it without testing whether it was true. 

Your heart is not the source of truth, but it can feel good in the moment to believe it is.

That our hearts will always lead us correctly in life is perhaps the most dangerous lie that pervades today. 

We all need a guiding principle to live by, but if it does not align with the Truth of who God is and what He is really like, we will be misguided. Believing our hearts are our guiding principle, or that simply “following your truth” will lead us correctly is simply false. We are not guarding our hearts wisely when we place it in a station in our lives higher than it was intended for. 

It is not popular to say that God’s Truth is the only truth. But, following a different principle only keeps us slaves to whatever lie we fancy most. 

Our false beliefs keep us in bondage, but only the Truth sets us free.

The thing is that deep down in a really honest place, our hearts know that they are not to be trusted to the level of a guiding principle. Over time, hearts fail us. They misguide us. They lie to us when we ask too much of them by treating them as the source of truth. But, when we surrender our hearts to the will of God, putting them in their rightful place under God’s authority, there they are properly guarded. There they will thrive. There our hearts can align with life itself and be the wellsprings that God intended. 

Friends, if you struggle with guarding your heart, I encourage you to ask for God’s help to test your own heart and see where you’re believing things that aren’t true, and where your will is coming against His. Trust that God knows what He is doing and that He knows what is best for your heart because He made it in the first place. No one knows your heart better than the Lord. Surrender your heart to Him today; you will never regret it. 

And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus” (Philippians 4:7).
