Read Introduction to 2 Peter


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


but grow

This verse begins with a contrast to verse seventeen. We need to “beware” (v.17), but we also need to “grow” (v.18). Some Christians never grow in their faith. They do not advance much beyond the point of their salvation.

The word “grow” means to increase, to extend. Spiritual growth is not an event; it is a process. Salvation is an event, but growth is a process.

“Grow” is a command; it is not an option. The Greek grammar also indicates that we are to keep on growing.


Growth is a process of becoming more like the Lord Jesus.


After we become Christians, we tend to pick up spiritual childhood diseases. We may even acquire some permanent spiritual scars from those diseases. Some people develop so many scars that they are afraid to make further spiritual advances. Others advance through the troubled teen period spiritually; that is spiritual adolescence. They are half teen, half adult. Yet, still, a few others gain spiritual maturity. This is the point when they become spiritual adults.

The spiritual life is like a bicycle; unless we keep moving, we fall off. None of us ever arrives at a state of spiritual perfection, but we should grow to be more like Christ every day. This is progressive sanctification, a lifelong process. The Spirit of God takes the Word of God and makes the child of God like the Son of God (Romans 8:29). We can become spiritually mature. 

Some Christians develop much faster than others do. Their rate of growth is rapid and exponential. These people usually have a great desire to change their lives and a hunger for what God says to them. They hold the Word of God in high regard (1 Peter 2:2) and believe God can change their lives. They appropriate truth to their experience daily. They cannot help but change into the same image of Christ from glory to glory by the Spirit of the Lord (2 Corinthians 3:18).

“But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord” (2 Corinthians 3:18).

Do you have a case of arrested spiritual development? Is your spiritual growth stunted? Are you developing your spiritual muscles? Do you work out physically but rarely exercise spiritually? If we yearn to grow, it must be a passion. It cannot be something that we give heed to once a week in a Sunday service. We need to work at becoming more spiritually mature daily. It is not something that comes naturally. God will supernaturally change us through His Word.

We never fully arrive at perfection in the Christian life, but if we continue to grow, we will never be spiritually static. We can become a mature believer.
