Guarding What God Has Put in Your Heart

I can’t tell you how many times I’ve heard messages on the importance of guarding our hearts. God wants relationships with people who are pure in heart and who are whole-heartedly devoted to Him. In order to be like that, we need to be careful what we let into our hearts. Guarding our hearts, we’re often told, is about not letting bad things in.

Though that aspect of guarding our hearts is of vital importance, there’s also another side to this. To quote a daily devotional I’ve been reading, “We are to keep things in –things like the Spirit of Jesus, the humility and gentleness, the servanthood and sacrifice, the worship and thankfulness” (Chris Tiegreen, 365 Pocket Devotions, p.23). We need to be careful that we’re not so focused on keeping bad things out that we forget to keep the good things in.

Keep Truth In Your Heart

When Samuel was sent to anoint David, Yahweh told him, “God does not view things the way people do. People look on the outward appearance, but the Lord looks at the heart” (1 Sam. 16:7, NET). What’s in our hearts is what matters most to God. We don’t want to let in things that would corrupt our hearts, but we’re also not evaluated based on what we’ve kept out. God looks at what we keep in.

My child, pay attention to my words;
listen attentively to my sayings.
Do not let them depart from your sight,
guard them within your heart;
for they are life to those who find them
and healing to one’s entire body.
Guard your heart with all vigilance,
for from it are the sources of life.

Proverbs 4:20-23, NET

This is the one Bible passage that clearly instructs us to guard our hearts. It starts out by telling us to put wise words inside us and then “keep them in the center of your heart” (v. 21, WEB). It’s about guarding the good things in our hearts because what’s inside us determines what comes out of our lives, for good or evil.

He said, “What comes out of a person defiles him. For from within, out of the human heart, come evil ideas, sexual immorality, theft, murder, adultery, greed, evil, deceit, debauchery, envy, slander, pride, and folly. All these evils come from within and defile a person.”

Mark 7:20-23, NET

If what’s inside our hearts is bad, the fruit our lives produce will be bad also, no matter how much we polish up the outside. We can, however, with God’s help, replace the bad things with good things. Change has to happen in our hearts as we internalize the words of God, and then we need to guard those good things that He gives us.

Attach Your Hearts to Good Things

Putting His law inside people’s hearts is one of the central aspects of God’s new covenant. When He prophesied the new covenant, He said, “I will put my law within them and write it on their hearts and minds. I will be their God and they will be my people” (Jer. 31:33, NET). That’s what’s happening as part of the covenant Jesus instituted with His sacrifice (Heb. 8:7-13; 10:14-18). In order to have good things come from our lives we need to have good things in our hearts, and that comes from entering this covenant with God. We also need to diligently guard what God is teaching and giving us.

“Don’t lay up treasures for yourselves on the earth, where moth and rust consume, and where thieves break through and steal; but lay up for yourselves treasures in heaven, where neither moth nor rust consume, and where thieves don’t break through and steal; for where your treasure is, there your heart will be also.”

Matthew 6:19-21, NET

Part of guarding our hearts involves being careful about what “treasure” we attach ourselves to. If the things that we care about most and pour our energy into are worldly, that’s where our hearts will be. But if we put our efforts, time, and affection into good and godly things, then that is what our hearts and souls will treasure.

Entrust God With Your Heart

There is one other verse that uses the phrase “guard your hearts.” This time, though, it’s not an instruction for us. It’s something God does for us when we trust Him with our hearts and minds.

Do not be anxious about anything. Instead, in every situation, through prayer and petition with thanksgiving, tell your requests to God. And the peace of God that surpasses all understanding will guard your hearts and minds in Christ Jesus.

Philippians 4:6-7, NET

We talked about this type of peace at length just a couple weeks ago in a post called “Finding Peace On Earth Today.” The peace that God offers is a sort of peace that’s not dependent on external circumstances. Rather, it is a product of a heart that is committed to fully trusting God. True, lasting, godly peace comes when we trust God to take care of the things that threaten to take away our peace. When we pray in every situation, God shares His peace with us and it works to guard our hearts.

The task of guarding our hearts–keeping good things in and stopping bad things from taking over–is a life-long process. It’s something that God expects us to be actively involved in, and it’s something that He’s committed to helping us with.
