The Second Commandment: Worshiping God as He Commands

We often assume that sincere worship must be acceptable worship. The second commandment lovingly corrects that assumption. Westminster Larger Catechism Question 107 asks, “What is the second commandment?” The answer is: “The second commandment is, ‘You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth. You shall not bow down to them or serve them, for I the LORD your God am a jealous God, visiting the iniquity of the fathers on the children to the third and the fourth generation of those who hate me, but showing steadfast love to thousands of those who love me and keep my commandments.’”

Question 108 then asks, “What are the duties required in the second commandment?” The answer is:

“The duties required in the second commandment are the following:

• receiving, observing, and keeping pure and whole all such religious worship and ordinances as God has instituted in his Word, particularly prayer and thanksgiving in the name of Christ;

• reading, preaching, and hearing the Word;

• the administration and receiving of the sacraments;

• church government and discipline, Christian ministry, and the support of it;

• religious fasting;

• swearing by the name of God and vowing to him;

• disapproving, detesting, and opposing of all false worship and, in accord with one’s role in this life and calling, removing false worship and all monuments of idolatry.”

Together, these questions teach that the God who deserves our worship also determines how he is worshiped.

The Second Commandment Protects True Worship

The first commandment tells us whom we must worship: the Lord alone. The second commandment tells us how we must worship him. We are to worship him according to his revealed will rather than our imagination. Israel was forbidden not only to worship pagan gods, but also to use an image as a means of worshiping the true God.

An image fashioned by human hands reduces the Creator to something within creation—a form we can see, manage, and control. But God is not ours to redefine. He has made himself known through his Word and, supremely, through his Son.

Moses therefore commanded Israel to take God’s words to heart: “For it is no empty word for you, but your very life” (Deuteronomy 32:46–47). Jesus likewise commissioned the church to teach disciples “to observe all that I have commanded you” (Matthew 28:20). Faithful worship begins with submission to God’s Word.

The Jealous Love Behind the Second Commandment

God calls himself “a jealous God.” Unlike sinful human jealousy, God’s jealousy is his holy commitment to his name and his covenant people. He will not share his worship with idols or allow us to remake him according to our preferences.

False worship is never harmless. It distorts our knowledge of God and passes its damage to later generations. Yet the promise shines even more brightly: judgment reaches “the third and the fourth generation,” but God’s steadfast love reaches thousands. The emphasis falls on his abundant mercy.

Before giving this commandment, God announces that he brought Israel out of slavery. Obedience does not purchase redemption; it is the grateful response of a redeemed people. Christians do not worship rightly to earn Christ’s favor. We seek pure worship because, in Christ, God has made us his own.

The Second Commandment and the Ordinary Means of Grace

Question 108 shows that obedience to the second commandment is not merely avoiding statues. We must receive and preserve the worship God has appointed. The early church “devoted themselves to the apostles’ teaching and the fellowship, to the breaking of bread and the prayers” (Acts 2:42). Through these ordinary means, Christ nourished his church.

God calls us to pray and give thanks in Christ’s name. We bring our requests to God “with thanksgiving” (Philippians 4:6) and thank the Father through the Lord Jesus Christ (Ephesians 5:20). Christian worship is God-centered, Christ-mediated, and grateful.

The second commandment also requires the reading, preaching, and hearing of Scripture. Ministers must “preach the word” (2 Timothy 4:2); hearers must receive it meekly and obey it (James 1:21–22). A sermon is not a performance. God addresses his people through Scripture, and they listen with faith and readiness to obey.

The Second Commandment in the Life of the Church

God has also given baptism and the Lord’s Supper to his church. Christ commanded baptism in the triune name (Matthew 28:19), and Paul taught believers to receive the Supper with reverent self-examination (1 Corinthians 11:23–30). We must neither neglect nor reshape these ordinances.

Church government, discipline, and ministry belong to Christ’s wise provision. Discipline seeks the restoration and purity of his people (Matthew 18:15–17), while pastors and teachers equip the saints for ministry (Ephesians 4:11–12). Supporting faithful ministry helps preserve the ministry of the Word (1 Timothy 5:17–18).

The catechism also names fasting, lawful oaths, and vows. Biblical fasting is a humbled return to God: “Rend your hearts and not your garments” (Joel 2:12–13). Oaths and vows must likewise honor God’s name (Deuteronomy 6:13; Psalm 76:11).

Keeping Worship Pure in Every Calling

Finally, the second commandment requires us to oppose false worship. Paul was distressed by the idols of Athens, yet he responded by reasoning from God’s truth (Acts 17:16–17). We must act according to our place and calling—not through private violence or self-appointed rule, but by removing idols from our hearts and homes, guarding the church’s worship where responsible, and testifying to the truth.

The second commandment asks more than, “Do I worship?” It asks, “Am I worshiping the true God in the way he has appointed?” Christ has given his church his Word, prayer, praise, sacraments, ministry, discipline, and other acts of devotion commanded in Scripture. Through these ordinary means, God feeds our faith and keeps our worship centered upon himself.

Let us not seek novelty when God has given us something better: worship shaped by his Word, offered through his Son, and empowered by his Spirit. The God who redeemed us is worthy not only of worship, but of worship as he commands.
