Base texts
- Ezekiel 14:1–5 – idols in the heart.
¹ Then certain of the elders of Israel came to me and sat before me. ² And the word of the LORD came to me: ³ "Son of man, these men have taken their idols into their hearts, and set the stumbling block of their iniquity before their faces. Should I indeed let myself be consulted by them? ⁴ Therefore speak to them and say to them, Thus says the Lord GOD: Any one of the house of Israel who takes his idols into his heart and sets the stumbling block of his iniquity before his face, and yet comes to the prophet, I the LORD will answer him as he comes with the multitude of his idols, ⁵ that I may lay hold of the hearts of the house of Israel, who are all estranged from me through their idols." (Ezekiel 14:1–5, ESV)
- Romans 1:23–25 – exchanging the glory of God for the creature.
²³ and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things. ²⁴ Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves, ²⁵ because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen. (Romans 1:23–25, ESV)
- Matthew 22:37 – to love God with all your heart.
³⁷ Jesus answered: "'You shall love the Lord your God with all your heart and with all your soul and with all your mind.'" (Matthew 22:37, ESV)
- 1 Corinthians 10:31 – "So, whether you eat or drink, or whatever you do, do all to the glory of God." (ESV)
- Romans 11:36 – "For from him and through him and to him are all things. To him be glory forever. Amen." (ESV)
- Westminster Catechism, Q.1 – the chief end of man.
Q. 1: What is the chief and highest end of man?
A: Man's chief and highest end is to glorify God, and fully to enjoy him forever.
- Calvin – "The human heart is a perpetual factory of idols" (Institutes 1.11.8).
1) We were created to worship God, not idols
1.1 The greatest commandment: to love God above all things
- Read Matthew 22:37–38: to love God with all your heart, soul, and mind.
³⁷ Jesus answered: "'You shall love the Lord your God with all your heart and with all your soul and with all your mind.' ³⁸ This is the great and first commandment." (Matthew 22:37–38, ESV)
- Our whole life should be centered on God – mind, affections, decisions, priorities.
1.2 Our purpose: to glorify God and enjoy him forever
- Read the answer of the Westminster Catechism, Q.1:
"Man's chief and highest end is to glorify God, and fully to enjoy him forever."
- That is: we were created to worship; the worship of God is the full reason for our existence.
1.3 Worship in practice: outward expressions of a surrendered heart
- Biblical examples of worship:
- Bowing down, revering, praising, praying, obeying (use figures such as Abraham, David, the early church).
- Principle: true worship begins in the heart and manifests itself in attitudes, words, priorities.
Transition:
If we were created to worship God like this, why do we end up living so much for other things (money, family, dreams, ourselves)?
2) The problem: the heart is a factory of idols
2.1 Ezekiel 14: religious leaders with idols in their hearts
- Read Ezekiel 14:1–5.
¹ Then certain of the elders of Israel came to me and sat before me. ² And the word of the LORD came to me: ³ "Son of man, these men have taken their idols into their hearts, and set the stumbling block of their iniquity before their faces. Should I indeed let myself be consulted by them? ⁴ Therefore speak to them and say to them, Thus says the Lord GOD: Any one of the house of Israel who takes his idols into his heart and sets the stumbling block of his iniquity before his face, and yet comes to the prophet, I the LORD will answer him as he comes with the multitude of his idols, ⁵ that I may lay hold of the hearts of the house of Israel, who are all estranged from me through their idols." (Ezekiel 14:1–5, ESV)
Observations:
- They are elders of Israel – religious people, leaders, "insiders".
- They sit before the prophet, as those who seek the will of God.
- But God reveals: "these men have taken their idols into their hearts".
Application:
- It is possible to be at the meeting, to sit before the Word, and still have a heart full of idols.
- Here you disentangle religious life from true worship: physical presence and the right speech do not guarantee a heart without idols.
2.2 Romans 1: exchanging the Creator for the creature
- Read Romans 1:23,25.
²³ and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things. ²⁴ Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves, ²⁵ because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen. (Romans 1:23–25, ESV)
Summary:
- "They exchanged the glory of the incorruptible God for images…"
- "They exchanged the truth of God for a lie, worshiping and serving the creature rather than the Creator."
Principle:
- Idolatry = exchanging God for something else, serving and loving the creature in place of the Creator.
2.3 Calvin: the heart as a factory of idols
- Quote John Calvin:
"The human heart is a perpetual factory of idols."
Explain:
- We never stop manufacturing gods – things we trust in, live for, that define our identity and security.
- They are not only statues; today, the idols are: relationships, careers, comfort, approval, control, family, money, dreams.
2.4 Practical examples of idolatry of the heart
Here are a few concrete examples (illustrate so the small group can identify with them):
- Money/success: living to earn more, measuring personal worth by the balance, sacrificing everything for it.
- Family/relationships: placing spouse/children in an absolute position, where we disobey God to please them.
- Personal dreams: making a plan (career, ministry, moving to another country, marriage) the condition of our joy.
- Image/self-esteem: living for approval, likes, appearance, not for the glory of God.
Key phrase:
"An idol is any good thing that becomes necessary, that takes the place of God in the heart."
2.5 How can I identify whether I have idols?
Diagnostic questions to share with the small group:
- What do I most fear losing?
- What makes me disobey God in order to keep it?
- What do I think about most when I am free?
- What, if God took it away, would make me feel that life had lost its meaning?
- What drives my decisions most: the will of God, or security, comfort, approval, personal fulfillment?
3) The path of true worship: from the throne of idols to the throne of God
3.1 God exposes the idols to call us to repentance
- In Ezekiel 14, God says he will not answer while the idols remain in the heart.
- He exposes idolatry in order to restore his people, bringing them back to himself.
3.2 Repentance: taking idols off the throne and enthroning God
Here, repentance goes well beyond just "feeling guilty". It is:
- Recognizing: "I have been worshiping something else in place of God".
- Confessing this as sin, not as "just a priority".
- Submitting that area to God: money, family, dreams, image – everything returns to being a gift, not a god.
3.3 Practical tips for focusing life on God and living to worship him
A few simple steps for the small group to put into practice:
a) Review the heart daily in the light of the Word
- Sincere devotional:
"Lord, show me what is taking Your place in my heart."
b) Reorder priorities in practice
- Schedule, money, rest, family, service in the church – everything organized starting from God, not the other way around.
c) Replace idols with conscious worship
- When you notice: "I am anxious/obsessed about this", turn it into prayer and surrender:
"Lord, this is important, but it is not God. You are my God."
d) Cultivate fellowship with the church and a life of corporate worship
- Not only consuming the service, but participating with a surrendered heart, knowing that true worship is life + lips, not just music.
e) Always remember the Gospel
- Only Christ can break the power of idols: He shows us a God more beautiful, more worthy, more satisfying than any idol.
