A New Heart That Loves God

How can a person obey the command to love when the heart itself is resistant?

Key passages

Deuteronomy 30:1–10; Jeremiah 31:31–34; Ezekiel 36:22–28; John 3:1–16; Romans 8:1–17; Titus 3:3–7.

Chapter thesis

The love God commands is also the love he promises to produce by giving a new heart, writing his law within, granting new birth, and indwelling believers by the Holy Spirit.

Promise beneath the command

Deuteronomy commands wholehearted love, but it also records Israel’s stubbornness. The book looks forward to a work only God can perform: circumcising the heart so that the people will love him. Jeremiah speaks of a new covenant in which God’s law is written within and sins are forgiven. Ezekiel promises cleansing, a new heart, a new spirit, and God’s own Spirit enabling obedience.

These promises prevent two opposite mistakes. The first is despair: “Because my heart is resistant, change is impossible.” The second is presumption: “Because God must act, my response is irrelevant.” The covenant promise creates active hope. God renews people so that they actually repent, believe, obey, and love.

New birth

Jesus tells Nicodemus that entry into God’s kingdom requires birth from above by the Spirit. Religious status, education, and moral seriousness cannot substitute for regeneration. The new birth is God’s sovereign work, mysterious in operation but visible in its effects.

Regeneration does not mean instant emotional maturity or the disappearance of temptation. It means a decisive new principle of life. The believer now sees Christ as desirable, grieves sin as sin against God, and begins to obey from a renewed center. These desires may be weak, conflicted, and obscured, but they were not present in the same saving form before.

The Spirit and adoption

Romans 8 joins liberation, holiness, adoption, prayer, suffering, and assurance. The Spirit sets believers free from the dominion of sin, enables them to put sinful practices to death, and bears witness that they are God’s children. Love grows not merely through a new rule but through a new relationship: “Abba, Father.”

The cry of adoption is not always emotionally dramatic. It may appear as a frightened believer still turning toward God rather than finally abandoning him. The Spirit helps weakness, intercedes in groaning, and keeps the Christian within the love of God in Christ.

Already renewed, not yet perfected

The New Testament holds together decisive change and continuing conflict. Believers have died and risen with Christ, yet must put sin to death. They possess the Spirit, yet groan while awaiting bodily redemption. They love God, yet their love is incomplete.

This explains why sincere Christians can experience contradictory desires. The presence of conflict does not prove absence of grace; settled peace with sin is more alarming. The question is not whether temptation speaks, but whether the believer increasingly brings it to Christ, resists it, and seeks obedience.

Voice from the church: Martin Luther

Luther’s central Reformation insight was that sinners are justified by faith apart from works and then freed to love and serve the neighbor. Faith receives before love gives. This protects renewal from becoming self-justification. The necessary qualification is that true faith is living and fruitful; grace is not permission to remain willingly under sin’s rule.

Important distinction

Regeneration is not self-reprogramming. Habits matter, communities shape us, and practices train attention, but only God gives spiritual life. The same truth does not make habits unimportant; renewed people are commanded to train themselves for godliness.

Praying for willing and doing

Philippians 2 gives the mature pattern: believers work because God is at work in them, both in willing and in doing. When desire is weak, pray not only for external help but for a changed will. Then act in dependence rather than waiting for a perfect internal state.

A useful prayer is, “Lord, I want to want what you want. Make me willing, and help me take the next faithful step.” This is not hypocrisy. Hypocrisy pretends to possess

what it refuses to seek. Honest dependence acknowledges weakness and moves toward obedience.

Chapter summary

God answers the resistant heart with new-covenant grace. He forgives, regenerates, indwells, adopts, and progressively transforms. Christian effort is real but responsive: we work because the Spirit is already working within us.

Reflect and discuss

1. Where do you confuse new birth with constant emotional intensity?

2. What evidence of a new direction - however incomplete - can you identify in your life?

3. Which area requires the prayer, “Work in me both willing and doing”?

Practice for this week

Memorize Ezekiel 36:26–27 or Philippians 2:13. Before one difficult act of obedience each day, pray the verse and then act.

Prayer

God of the new covenant, I cannot heal my own heart. Cleanse me, renew my desires, and fill me with your Spirit. Let the freedom of adoption produce willing obedience, patient repentance, and growing love. Amen.
