1 Cor 14:20 & Eph 4:14 on maturity?
How does 1 Corinthians 14:20 connect with Ephesians 4:14 about maturity?

Growing Up in Christ’s Classroom

1 Corinthians 14:20: “Brothers, stop thinking like children. In regard to evil be infants, but in your thinking be mature.”


Connecting the Dots: 1 Corinthians 14:20 + Ephesians 4:14

Ephesians 4:14 parallels the call: “Then we will no longer be infants, tossed about by the waves and carried around by every wind of teaching…”

• Both verses spotlight two sides of Christian growth:

– Innocence toward evil (infants regarding malice)

– Stability and discernment in doctrine (mature thinking)


Childlike Innocence vs. Childish Instability

• “Be infants in regard to evil”

– Stay untainted, refuse fascination with sin (Romans 16:19).

• “In your thinking be mature”

– Cultivate solid, reasoned faith able to test everything (1 Thessalonians 5:21).

Ephesians 4:14 fleshes this out: maturity anchors believers so false teaching can’t toss them around like waves.


Why Maturity Matters

• Protects from deception (Colossians 2:8).

• Equips believers to speak truth in love (Ephesians 4:15).

• Enables steady, fruitful lives (Psalm 1:2-3).


Picture of the Process

1. Start with pure spiritual milk (1 Peter 2:2).

2. Progress to solid food—deeper doctrine and obedient practice (Hebrews 5:12-14).

3. Grow into Christ, the Head, joined and held together (Ephesians 4:15-16).


Maintaining Innocence without Naivety

• Filter entertainment and information through Philippians 4:8.

• Confess sin quickly (1 John 1:9) to keep heart tender.

• Stay alert to evil schemes while resisting them (2 Corinthians 2:11; James 4:7).


Practical Steps Toward Mature Thinking

• Daily Scripture intake and memorization (Joshua 1:8).

• Active participation in a Bible-teaching church (Acts 2:42).

• Serve with spiritual gifts—exercise builds strength (1 Corinthians 12:7).

• Invite wise counsel; iron sharpens iron (Proverbs 27:17).

• Practice discernment: compare every idea with God’s Word (Acts 17:11).


End Goal

Colossians 1:28 captures the heartbeat: “We proclaim Him, admonishing and teaching everyone with all wisdom, so that we may present everyone perfect in Christ.”

The journey from spiritual infancy to Christ-like maturity unites 1 Corinthians 14:20 and Ephesians 4:14: innocent hearts, discerning minds, steadfast lives.
