2 Peter 3:18 & Eph 4:15 on growth?
How does 2 Peter 3:18 connect with Ephesians 4:15 about spiritual growth?

Foundation Verse: 2 Peter 3:18

“But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and to the day of eternity. Amen.”


Parallel Truth: Ephesians 4:15

“Instead, speaking the truth in love, we will in all things grow up into Christ Himself, who is the head.”


Shared Themes of Growth

• Same Direction—toward Christ

– 2 Peter: “our Lord and Savior Jesus Christ.”

– Ephesians: “grow up into Christ Himself.”

Both writers fix our trajectory on Christ, not mere self-improvement.

• Same Dynamic—active, continual progress

– “Grow” (present imperative, 2 Peter) = keep advancing.

– “Grow up” (future plural, Ephesians) = an expected outcome as we obey.

• Complementary Means

– Grace and Knowledge (2 Peter)

▪ Depend on God’s empowering favor (2 Corinthians 12:9).

▪ Pursue doctrinal depth (Colossians 1:9-10).

– Truth and Love (Ephesians)

▪ Speak Scripture truthfully (John 17:17).

▪ Deliver that truth lovingly (1 Corinthians 13:1-2).

Put together, we grow by embracing grace, gaining knowledge, speaking truth, and expressing love.

• Corporate Dimension

– Peter writes to the church family (2 Peter 1:1).

– Paul addresses the body “joined and held together” (Ephesians 4:16).

Spiritual maturity is never isolated; God grows us in community (Hebrews 10:24-25).

• Ultimate Aim

– Glory to Christ “both now and to the day of eternity” (2 Peter).

– Conformity to Christ, our Head (Ephesians).

Growth is worship: His glory is displayed as His likeness increases in us (Romans 8:29).


Practical Take-Aways

• Start each day conscious of grace; end each day adding knowledge (2 Peter 1:5-8).

• Let truth saturate your speech; let love season your tone (Proverbs 16:24).

• Engage the whole body—small groups, worship, mutual encouragement—to “build itself up in love” (Ephesians 4:16).

• Measure progress by Christ-likeness, not comparison with others (Philippians 1:9-11).

Grace, knowledge, truth, and love converge so that every believer—and every congregation—moves steadily toward full maturity in Christ, bringing Him glory now and forever.
