Building a Life That Lasts: Growing in Faith
In a world where it’s easy to start strong but fade away, how do we build a Christian life that endures? The Apostle Peter, writing what would be his final letter before martyrdom, gives us urgent wisdom about cultivating a faith that lasts all the way to the finish line.
Why Peter’s Final Words Matter
Second Peter isn’t just another New Testament book to casually read through. This letter carries the weight of a dying man’s final words. Peter knew his death was approaching when he wrote: “For our Lord Jesus Christ has shown me that I must soon leave this earthly life” (2 Peter 1:14).
When people know their time is limited, they don’t waste words. They share what matters most. Peter’s urgent message to the early church – and to us today – focuses on one critical truth: we must remain faithful and keep growing in Christ until we reach the finish line.
What Does It Mean to Have a Strong Faith?
A strong life of faith is a life that keeps growing. This isn’t about quick bursts of enthusiasm that burn out after a few months. True Christian faith is meant to be cultivated and strengthened throughout our entire lives.
Peter addresses believers who, like many Christians today, face the danger of spiritual drift. In America especially, it’s easy to start with excitement but gradually lose sight of what matters for eternity. The Christian life requires intentional growth, not passive hoping.
God Has Given Us Faith to Grow
Before Peter tells us how to grow, he establishes our foundation. In 2 Peter 1:1-2, he writes: “This letter is from Simon Peter, a slave and an apostle of Jesus Christ. I’m writing to you who share the same precious faith that we have. This faith was given to you because of the justice and fairness of Jesus Christ, our God and Savior.”
Notice the phrase “precious faith.” Peter, who walked with Jesus, denied Him in fear, was restored by grace, and ultimately died as a martyr, tells us we have received the exact same precious faith he had. This faith wasn’t earned or generated by us – it’s a gift from God.
Faith Comes Through God’s Righteousness
Our faith comes “through the righteousness of our God and Savior Jesus Christ.” This means God didn’t ignore our sin or play favorites. Because He is holy and righteous, He couldn’t simply overlook sin. Instead, He made a perfect plan: Jesus came to earth, took our sin upon Himself, died in our place, and rose again in victory.
Your faith is precious because it was purchased by the blood of Jesus, rests on His righteousness, and was given to you by God’s grace. This is your foundation – solid, secure, and perfect.
God Has Given Us Everything We Need
Peter makes an incredible statement in verse 3: “By his divine power, God has given us everything we need for living a godly life.” This is remarkably clear – if you’re a believer, you’re not spiritually under-equipped.
God hasn’t shortchanged any Christian. You don’t need to wait for another emotional mountaintop experience or the next season of life to start growing. You don’t need more conferences or special events, though these can be helpful tools.
What Has God Already Given Us?
Through salvation, God has provided:
- The Holy Spirit’s power in our lives
- His Word and promises
- Access to Him through prayer
- The church community
- A new nature that can reflect His character
Peter says we “share his divine nature” – not that we become gods, but that we receive new life, a new heart, new direction, and new purpose. We’re no longer slaves to this world’s corruption but have been called to represent God to a dying world.
Why Do So Many Believers Fail to Grow?
If God has given us everything we need, why do so many Christians fail to mature? The answer lies in cultivation. An acorn contains everything necessary to become a mighty oak tree, but it still needs watering, good soil, and care to reach its potential.
Similarly, when God saves us, we receive everything needed for spiritual growth. But that growth isn’t automatic – it requires intentional cultivation through:
- Regular time in God’s Word
- Consistent prayer and communication with God
- Obedience to His commands
- Active participation in Christian community
It’s Time to Start Building
In verse 5, Peter shifts from what God has done to what we must do: “In view of all this, make every effort to respond to God’s promises.”
Notice he says “make every effort.” Spiritual growth doesn’t happen by accident. You don’t drift into Christ-likeness or wake up one day suddenly mature. Any job done well requires effort, and spiritual growth is no exception.
The Building Blocks of Christian Character
Peter provides a specific blueprint in verses 5-7: “Supplement your faith with a generous provision of moral excellence, and moral excellence with knowledge, and knowledge with self-control, and self-control with patient endurance, and patient endurance with godliness, and godliness with brotherly affection, and brotherly affection with love for everyone.”
These qualities build upon each other like blocks in a foundation:
- Faith – The foundation God provides
- Moral excellence – Living with integrity and righteousness
- Knowledge – Growing in understanding of God and His ways
- Self-control – Bringing areas of life under Christ’s lordship
- Patient endurance – Staying faithful when quitting seems easier
- Godliness – Reflecting God’s character in daily life
- Brotherly affection – Showing grace to fellow believers
- Love for everyone – The ultimate goal of Christian maturity
Notice where this list ends: with love. Christian maturity always heads toward learning to love like Christ – a love that serves, forgives, sacrifices, and puts others first.
Where Are You in Your Construction Phase?
These building blocks can’t be skipped. You can’t have Christ-like love without first developing moral excellence, self-control, and patient endurance. So where are you in your spiritual construction?
Maybe you need to work on moral excellence – addressing sin in your life that needs to be confessed and abandoned. Perhaps it’s self-control – bringing priorities or habits under Christ’s lordship. It might be endurance – staying faithful in a difficult situation where quitting would be easier.
Or maybe God is calling you to show brotherly affection to someone who isn’t easy to love, or to develop that sacrificial love that characterizes mature believers.
Growth Leads to Fruitfulness and Endurance
What’s the point of all this growth? Peter explains in verse 8: “The more you grow like this, the more productive and useful you will be in your knowledge of our Lord Jesus Christ.”
Growth produces fruit. A cultivated faith doesn’t stay hidden but shows up in how we live, shapes our character, strengthens our obedience, and deepens our love for others. As our lives change, we affect the lives of those around us.
The Danger of Not Growing
Peter gives a sobering warning in verse 9: “But those who fail to develop in this way are short-sighted or blind, forgetting that they have been cleansed from their old sins.”
When we stop growing, we don’t simply stay where we are – we begin sliding backward. If faith isn’t cultivated, something else takes root. Sin doesn’t sit quietly, and the world never stops pulling at our hearts.
A believer who stops growing becomes spiritually nearsighted, losing sight of eternity and living only for what’s immediately in front of them. The daily benefits of faith – peace, joy, clear conscience, strength in obedience – begin to fade.
The Promise of a Grand Entrance
Peter concludes with an incredible promise in verse 11: “Then God will give you a grand entrance into the eternal kingdom of our Lord and Savior Jesus Christ.”
This paints a picture of an extravagant, celebratory entrance into heaven – like a parade with streamers and fireworks. It’s the welcome of a Savior who is thrilled to see a faithful follower who has grown and endured to the end.
But a stagnant believer who refuses to cultivate their faith surrenders this joy and fruitfulness. They may still be saved, but they risk reaching the finish line with little spiritual fruit, barely making it through heaven’s gates having wasted much of what God placed in their hands.
Life Application
God has given you precious faith and everything you need for spiritual growth. Now it’s time to build. This week, read 2 Peter 1:5-7 several times and ask God to show you one specific area where He wants you to grow. Don’t try to rebuild your entire spiritual life in one afternoon – pick one building block to focus on.
Maybe it’s moral excellence and you need to address a specific sin. Perhaps it’s self-control and you need to surrender an area of your life to Christ’s lordship. It might be endurance and you need to stay faithful in a difficult situation. Or maybe it’s love and you need to show Christ-like grace to someone who’s hard to love.
Ask yourself these questions:
- Which building block of Christian character do I most need to work on right now?
- What specific step of obedience can I take this week to grow in that area?
- Am I cultivating my faith through regular time in God’s Word and prayer?
- What evidence of spiritual growth can I see in my life over the past year?
Remember, a strong life of faith is a life that keeps growing. God has equipped you with everything you need. Now make every effort to build a life that will be faithful to the finish – one that will earn you that grand entrance into His eternal kingdom.
