What the Bible means by maturity
In the New Testament, the word often translated “mature,” “perfect,” or “complete” (the Greek teleios) carries the sense of reaching an intended goal or being fully grown. It is not usually about flawlessness. Maturity in these passages tends to describe stability, discernment, love, and perseverance, and it is linked to Christ as the standard.
Key verses on maturity
Moving beyond the basics
- Hebrews 5:11-6:3. The writer says that some readers still need “milk” when they should be ready for solid food, and urges them to go on toward maturity (6:1). Verse 5:14 says solid food is for those who have trained their senses to discern good and evil.
- 1 Corinthians 3:1-3. Paul tells the Corinthians he could not address them as spiritually mature because of jealousy and quarrelling. Our lessons from 1 Corinthians 2 also touch on this passage and the “mature” of 2:6.
Stable, truthful and loving
- Ephesians 4:11-16. The goal is that believers are no longer “tossed to and fro” by every wind of teaching, but, “speaking the truth in love,” grow up into Christ (verses 14-15).
- 1 Corinthians 14:20. Paul asks the Corinthians not to be children in their thinking: be infants in evil but mature in thinking.
- 1 Corinthians 13:11. When Paul became an adult, he put away childish ways. This sits within the chapter on love.
Maturity through trials
- James 1:2-4. Testing of faith produces endurance, and endurance is allowed to finish its work so that readers may be “perfect and entire, lacking nothing” (KJV wording).
- Romans 5:3-4. Suffering produces endurance, character and hope. Both passages should be read gently: they do not say that suffering is good in itself, and they are not an invitation to minimize someone’s pain.
Pressing on
- Philippians 3:12-15. Paul says he has not already obtained or been made perfect, yet he presses on, and then speaks of those who are “perfect” (mature) sharing this mind. The same writer uses both ideas.
- Colossians 1:28. Paul’s aim is to present everyone mature in Christ.
Growth in character
- 2 Peter 1:5-8. Faith is supplemented with goodness, knowledge, self-control, steadfastness, godliness, affection and love.
- Galatians 5:22-23. The fruit of the Spirit. For a youth-friendly study, see Fruits of the Spirit Bible study for youth.
What does God say about change and growth?
Scripture presents change as both God’s work and a human response. Passages such as Romans 12:2 (being transformed by the renewing of the mind), 2 Corinthians 3:18 (being transformed into the Lord’s image), and Philippians 2:12-13 (working out salvation while God works in believers) are often read together. Traditions weigh the emphasis differently, but most say that growth does not earn salvation and that it is not finished in this life. Jesus is described as growing too: “in wisdom and stature” (Luke 2:52). For a wider survey, see Bible verses about growing in Christ.
What is Philippians 4:13 saying?
Philippians 4:13 is often quoted as “I can do all things through Christ which strengtheneth me” (KJV). In context, Paul has just written that he has learned to be content whether he has plenty or is in need (4:11-12). Many interpreters therefore read “all things” as the ability to endure every circumstance, rather than a promise of success in any goal. Maturity here looks like contentment and dependence on Christ’s strength.
What is Colossians 3:17 saying?
Paul writes that whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through him. It follows a list of qualities such as compassion, kindness, humility and patience (3:12-14). A mature life, on this reading, is one where ordinary speech and work are done thankfully and in line with Christ. The verse is discussed further in the identity in Christ study questions.
Signs of maturity the Bible describes
Without making it a scorecard, passages point to:
- steadiness rather than being easily swayed (Ephesians 4:14);
- speaking truth with love (Ephesians 4:15);
- discernment (Hebrews 5:14);
- perseverance in difficulty (James 1:4);
- fruit of the Spirit (Galatians 5:22-23);
- humility and ongoing willingness to learn (Philippians 3:12).
Cautions
- Age is not maturity. Paul urges Timothy that no one should look down on his youth (1 Timothy 4:12).
- Do not use maturity to rank people. Comparing yourself with others is warned against. See what the Bible says about comparison.
- Struggle is not proof of immaturity. Tiredness, grief and mental health challenges are not signs of weak faith. If you are struggling, a doctor or licensed counselor can help alongside your church.
Reflection questions
- Which verse above describes a part of life where you want to grow?
- Where might you be staying on “milk” because solid food feels uncomfortable?
- Who is a person whose steadiness you admire? What do you see in them?
- How does your group or church help people grow together?
