Hebrews 4:7b (Psalm 95:7b–8a)
Today, if you hear his voice, do not harden your hearts.
In Scripture, sometimes the word “today” is not about hours and minutes. Sometimes it is an eternal moment into which God is speaking. His voice is not merely something others heard once upon a time, nor is it simply something we must wait until heaven to hear. God assumes you will hear His voice. What He does not assume, however, is what will happen next. He warns us, “When you hear his voice, do not harden your hearts.”
A hard heart does not necessarily begin with an outright rejection of God. Scripture describes something more subtle. It warns us not “to be hardened by the deceitfulness of sin” (Hebrews3:13). Sin is deceitful because it captures our attention by promising something good while gradually turning our hearts away from God. We can become preoccupied with pleasures, comforts, achievements, possessions, recognition, security, or even our own problems.
The problem is not that the object of our attention is intrinsically evil. The danger comes when a good gift becomes the object of obsessive desire—when our hearts begin to say, “I must have this in order to be okay.” When something begins to occupy our thoughts repeatedly, we obsess. We turn it over in our minds. We imagine what it would be like to have it, or we fear losing it, or resent someone who possesses it, or become consumed with figuring out how to obtain it.
At that point, something else is happening beneath the surface. Gratitude is gone. Our heart is becoming hardened against God, our Father, the giver of every good gift. A hardened heart is not simply a heart that refuses to believe. It is a heart that has become less responsive to God's voice because something else has become more compelling.
If sin narrows our attention around some created thing, Christ enlarges our hearts by directing our attention toward something infinitely greater: His love. The antidote to the obsessive desires that harden our hearts is therefore not merely greater self-discipline. It is a deeper appreciation of Christ's love. In the New Covenant, God does not merely command us to have better hearts. He keeps His promise to give us a new heart, along with the forgiveness of our sins and the gift of the Holy Spirit.
Therefore, when we discover our hearts becoming preoccupied with something other than God, we do not need to despair. We can repent. Repentance means bringing our actual thoughts and desires into the light of God's Word:
“Lord, I have been thinking about this constantly.”
“Lord, I have begun to believe that I cannot be happy without this.”
“Lord, I have allowed this achievement to become the measure of my worth.”
“Lord, I have been looking to this comfort to give me the peace that only You can give.”
And then we can give thanks. Not because our hearts are already perfect, but because Christ has died for our sins and is has been raised to deliver to us a righteousness that is from God and is ours by faith. We can thank God for the new heart He has given us in Christ. We can thank Him that His Spirit dwells within us. We can thank Him that we are not abandoned to the tyranny of our obsessive desires. So “renewing” our participation in the New Covenant is not a matter of trying to manufacture a new heart every morning. It is returning in faith to the covenant God has already established in Christ.
Prayer: Good Shepherd, today give me ears to hear Your voice with a heart that does not become hardened by the deceitfulness of sin. Teach me to recognize when good gifts have become objects of obsessive desire, and give me grace to repent and return to You. Thank You for the New Covenant established in Christ, for the forgiveness of my sins, and for the new heart and new spirit You have given me by Your grace. Renew in me each day gratitude for what You have already done. Enlarge my heart to know the breadth, length, height, and depth of Christ's love—a love that is greater than every pleasure, comfort, achievement, or security I could ever pursue. Amen.
