Introduction

In this session, Romans 3: 1-20, we focus on the words the father of the two sons spoke, showing that both Jews and Gentiles have missed the mark of right living and are in need of a savor; no one has an advantage over the other. He pointed out seven sins or things that show that both brothers, Jews, and Gentiles, are not right before God and therefore need a savoir.

Objectives

By the end of this session, the learner will have:

  • Understood the Jewish brother’s advantage over the gentile by showing how he became unfaithful, but God remained faithful
  • Understood the seven qualities, which shows that both the Jews and the gentile have missed the mark of being right before the Holy Father and are in need of a savoir

Outline

  • Both Jews and Gentiles are lost and in need of a savoir
  • Faithfulness and unfaithfulness
  • The righteous discussed

Winning the souls of the lost two sons

Romans 3: 1-20

Romans 3:1-20

  • Context:
    • Romans 3:1-20 depicts God as a righteous father addressing His two sons (Luke 15:11-32): the Jew (firstborn) and Gentile (prodigal), both needing salvation.
    • Jews, entrusted with God’s oracles, were meant to bless Gentiles (Genesis 12:1-3), but failed, while Gentiles were bound by sin, self, and worldly systems.
  • Privilege and Failure (Romans 3:1-8):
    • The father asks, “What advantage is there in being a Jew?” (v. 1)—answering: great, as they received God’s Word first (v. 2), tasked to share it.
    • Jews’ unfaithfulness (not reaching Gentiles) doesn’t nullify God’s faithfulness (v. 3-4); their sin highlights His righteousness, but sinning to showcase it is condemned (v. 5-8).
  • Universal Sinfulness (Romans 3:9-18):
    • Both sons lack advantage; “Jews and Gentiles alike are under the power of sin” (v. 9), proven by Scripture (e.g., Psalm 14:1-3):
      1. No one is righteous or understands (v. 10-11).
      2. No one seeks God; all turn away, worthless (v. 11-12).
      3. Speech is deceitful, cursing, bitter—like open graves (v. 13-14).
      4. Actions shed blood, ruin lives, ignore peace (v. 15-17).
      5. No fear of God (v. 18).
  • Purpose of the Law (Romans 3:19-20):
    • Law speaks to Jews, silencing boasts and holding all accountable (v. 19); it reveals sin, not righteousness, showing both sons’ need for a Savior (v. 20).
  • Application:
    • The father exposes both sons’ guilt—Jews for suppressing truth via disobedience, Gentiles via rejection—leveling them as sinners needing grace to escape condemnation.

Gathering a Small Group

Start small to build a safe space for sharing and growth.

  • Pray first: Ask God to show you 3-6 people who need encouragement in faith, like family, neighbors, or fellow believers facing hardship.
  • Invite personally: Meet one-on-one, explain how the lessons are designed to help people grow in their faith and knowledge of God and his Word.
  • Keep it simple: Meet in a home or quiet spot; no need for fancy setup – just willing hearts.
  • Aim for consistency: Suggest weekly meetings, but be flexible for busy lives or safety concerns in persecuted areas.

Trust helps everyone open up, reflect, and apply truths without fear.

  • Start with sharing: In the first meeting, share simple stories of your own faith struggles to show vulnerability.
  • Set ground rules: Agree to listen without judging, keep stories private, and focus on encouraging each other.
  • Build bonds: Begin each session with a short prayer or song inviting God to be present with you.
  • Be patient: Trust grows over time – encourage quiet members gently, and celebrate small steps of honesty.

Good preparation makes the lesson flow and helps discipleship.

  • Read ahead: Study the lesson before; pray over the Bible passage and think how it fits your group’s challenges.
  • Adapt for the group: Use simple words; if literacy is low, read aloud slowly and explain questions or stories.
  • Gather basics: Have a Bible (in your language) and paper for notes.
  • Reflect personally: Ask yourself the study questions first – lead from your own growth and experience.
  • Pray: Pray for your group members.

Guide the group through the lesson structure to encourage discovery and commitment.

  • Step 1 – Connecting: Start the group meeting by praying together. Thank God for his Word and ask for open hearts to receive it. Read the Bible passage together (Read it aloud twice; ask someone to repeat in their words.)
  • Step 2: Comprehending: Use the provided questions to help you grapple with the truth of the Bible passage.
  • Step 3 – Committing: Consider how the passage might apply to your lives and what simple steps of obedience you can commit to. The goal of these studies if life-change! Not just knowledge!
  • Step 4 – Communicating:  Think of who you can share the truths you have learned with.
  • Close with Prayer: Let group members pray short prayers of thanks or commitment. Pray for one another.

For many of the lessons, there is a short summary teaching voice-note at the end of the lesson (together with a text summary). This is designed to be a recap and reminder of the key lessons you should have learned through the lesson. 

As a leader, you might like to use these summary teaching resources to help you in preparation for leading your group, though ideally not before you have spent time prayerfully reflecting on the passage.

This is an ongoing discipleship journey aiming to transform lives and help people to live victorious Christian lives. Focus on growth, not just finishing lessons.

  • Meet regularly: Join together at least once a week. Review past actions at each start to build accountability.
  • Encourage reflection: Between meetings, urge personal time with the lesson – read, pray, and try complete commitments made.
  • Support one another: If your group members are facing challenges, use lessons to pray together and share burdens; become “agents of change” by helping others in your community.
  • Multiply groups: As trust grows, encourage members to start their own small groups with family or friends.
  • Keep it short: Stick to 15 – 25 minutes per lesson to fit busy, challenging lives.
  • Handle challenges: If fear or hardship arise, encourage members by always pointing back to God’s love. 
  • Stay safe: In persecuted areas, meet discreetly; focus on heart change over big displays.
  • Celebrate progress: Note how people have grown in faith; allow time for sharing testimonies of what God has done. Take note of what you pray for, and give thanks when God answers prayer.

Final encouragement

Leading these lessons is serving like Jesus – humble, loving, and truthful. As you journey together, God will build growing faith into each person’s life. Pray often, and watch lives transform!
