What to Teach New Believers: A 12-Week Path from the Gospel to Mission

Teach new believers the essentials of the faith in an order that builds: the gospel, God, Scripture, sin, union with Christ, sanctification, the means of grace, a renewed mind, the church, baptism and the Lord's Supper, gifts and service, and perseverance and mission. Twelve meetings, weekly or every two weeks, cover that ground without skipping anything essential. Below is each topic in order, with its base text, what the new believer should take away, and one question to ask.

The twelve topics, in order

The question at the end of each topic shows whether the truth has reached the person, not only their notes.

1. The gospel: the center of everything

Base text: Ephesians 2:1-10.

Takeaway: We were dead in sin, and God made us alive in Christ. Salvation is a gift received by faith; good works are its fruit, not its price.

For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. (Ephesians 2:8-9, ESV)

The Shorter Catechism calls justification "an act of God's free grace," received "by faith alone" (WSC Q. 33), and the 1689 teaches the same (LBCF 11).

Ask: "If a friend asked you tomorrow how a person is made right with God, what would you say?"

2. Who is God? Holiness and grace

Base texts: Isaiah 6; Psalm 103.

Takeaway: God is holy, which is why sin is serious, and gracious, which is why there is hope. Teach both, and why knowing him matters: "Man's chief end is to glorify God, and to enjoy him forever" (WSC Q. 1).

Ask: "Which is harder for you to believe: that God is that holy, or that he is that kind?"

3. The Word of God: authority and sufficiency

Base text: 2 Timothy 3:16-17.

Takeaway: Scripture is breathed out by God, so it carries his authority, and it is enough to equip the believer for every good work. Both confessions begin here (WCF 1; LBCF 1). Send them home with a simple reading plan.

Ask: "When the Bible says one thing and your feelings or your upbringing say another, which one wins?"

4. Man and sin: the need for Christ

Base text: Romans 3.

Takeaway: Everyone has sinned, and no one is justified by keeping the law. The chapter then turns to righteousness given through faith in Christ (3:21-26), so do not stop before verse 21.

Ask: "Romans 3:11 says no one seeks for God. What does that tell you about your own conversion?"

5. New life and union with Christ

Base texts: 2 Corinthians 5:17; Galatians 2:20.

Takeaway: The believer is in Christ, a new creation, and Christ's death and life are counted as theirs. Identity comes before activity: they obey because they belong to him, not in order to belong.

Ask: "On a bad day, what would change if 'in Christ' were the first thing you believed about yourself?"

6. Sanctification: struggle, Spirit, and hope

Base text: Romans 8.

Takeaway: There is no condemnation for those in Christ, yet the fight with sin goes on. The Spirit is at work, growth is real but gradual, and the struggle ends in glory. Saying so early keeps disappointment from turning into doubt.

Ask: "Which sin did you expect to disappear when you came to faith, and how has that fight gone?"

7. Means of grace: Word, prayer, and fellowship

Base text: Acts 2:42.

Takeaway: God grows his people through ordinary means, which the Shorter Catechism sums up as "the word, sacraments, and prayer" (WSC Q. 88). Habits form here: Lord's Day worship, daily Scripture, prayer, friendships in the church.

Ask: "What would an ordinary week of Word, prayer and fellowship look like in your real schedule?"

8. A renewed mind: the Christian worldview

Base text: Romans 12:1-2.

Takeaway: The whole of life is worship. Scripture renews the mind, so that work, money, relationships and entertainment are seen in God's light instead of the world's.

Ask: "Where does the world shape your thinking most without your noticing: work, money, relationships or your phone?"

9. What is the Church? Body, membership, and unity

Base text: Ephesians 4.

Takeaway: One body, one Spirit, one Lord, one faith. Christ gives pastors and teachers to equip the saints for the growth of the whole body. Membership is mutual commitment to a local church under its elders. Both confessions give a chapter to the church (WCF 25; LBCF 26).

Ask: "What would it cost you to commit to this church, and what would you gain?"

10. Baptism and the Lord's Supper: signs of the covenant

Base texts: Matthew 28:18-20; 1 Corinthians 11:23-26.

Takeaway: Christ gave his church two visible signs. Baptism in the triune name marks entrance into the visible church. The Supper proclaims the Lord's death until he comes and nourishes faith.

Reformed churches differ here. Presbyterian churches baptize those who profess faith and also the infants of believing parents (WCF 28.4; WSC Q. 95). Reformed Baptist churches baptize those who actually profess repentance and faith in Christ (LBCF 29.2), and the 1689 calls both signs ordinances (LBCF 28.1). Teach what your church confesses, and describe the other view as its own holders would.

Ask: "Why do you think Christ gave us something to see and taste, and not only something to hear?"

11. Gifts and service: life in the body

Base text: 1 Peter 4:10-11.

Takeaway: Every believer has received a gift, given for serving others so that God is glorified in everything. Service is part of how maturity grows, not a reward for it.

Ask: "Where could you serve in this church in the next month?"

12. Perseverance and mission: walking to the end

Base texts: Philippians 1:6; Matthew 28.

And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ. (Philippians 1:6)

Takeaway: God finishes what he starts. Those he has called and sanctified will persevere to the end (WCF 17.1; LBCF 17.1), through the means of grace and not apart from them. The last meeting also sends the disciple out to help make disciples.

Ask: "Who in your life needs to hear what you have learned in these twelve meetings?"

Why does the order matter?

Sessions 1 to 5 cover what God has done; 6 to 8, how the believer grows; 9 to 11, life in the body; 12, the long road and the mission.

That order guards against two common mistakes. One is teaching duties before grace, so the new believer hears the Christian life as a list of things to do to stay accepted. The other is skipping the hard topics, sin above all, because the person seems eager and the meetings are pleasant. A fixed sequence prevents both. It also puts the church, the sacraments and service last, so people know what they are joining.

How should the emphasis change for different backgrounds?

The topics stay the same. What changes is where you slow down.

• Catholic background. Give the most care to the gospel of grace (session 1), the sufficiency of Christ, and Scripture as the authority (session 3). Treat baptism and the Supper without aggressiveness. They may love the parish that first taught them about Christ; they should not have to defend it to learn from you.
• Pentecostal background. Many arrive with a real love for prayer and an expectation that God acts. Give the most care to the Word governing experience (session 3), to sanctification as a progressive work (session 6) and to security in Christ (session 12).
• Returning to the faith. Begin with welcome. Then lead them back to the means of grace (session 7) and to hope, answering guilt with the gospel (session 1) rather than with a list of things to prove.

Adjust to Bible knowledge too: explain every term for a beginner, and go further into the confession with someone who has read for years.

One on one or with a group?

Both work. One on one lets you shape every meeting around the person: their story, their questions, the sin they are fighting.

A small group works when its members share a profile. Put a former Catholic and a former Pentecostal together, and the emphases above pull in different directions. Either way, a curriculum does not disciple anyone. People do, over an open Bible and honest conversation.

How long does a new believers class take?

Plan twelve meetings of 45, 60 or 75 minutes. Weekly, that is about three months; every two weeks, about six, with more room for reading and practice in between.

A simple shape for each meeting:

1. Welcome and a question about the past week.
2. Read the base text aloud and state its central idea in one sentence.
3. Explain the text and the doctrine.
4. Talk through the question.
5. Agree on a practice for the week: a reading, a prayer, one concrete step.
6. Close in prayer.

Shorter meetings need a short explanation; longer ones leave room for the person's own questions, which often matter most.

How does this prepare someone for profession of faith and membership?

Sessions 9 to 11 cover the church and membership, baptism and the Lord's Supper, and gifts and service, so the path ends where membership begins. By the last meeting, the new believer should be able to say in their own words what they believe about the gospel, why they want to belong to this church and what the signs Christ gave mean.

That is the conversation the elders will want to have. In Presbyterian churches, the session usually hears a profession of faith before receiving someone as a communicant member. In Reformed Baptist churches, the elders usually hear the person's testimony before baptism and membership. Either way, go over your membership vows or church covenant in the final weeks.

What to do this week

• Name one new or returning believer you could meet with.
• Choose a rhythm and a length you can keep.
• Read Ephesians 2:1-10 and decide which question you will ask first.
• Tell your elders, so the path ends in a conversation with them.

If you want each session drafted around the disciple's background, age and Bible knowledge, with a guide for you and a sheet for the disciple, see how the discipleship curriculum works in Hokmah Expositor. The sequence above stands on its own either way.
