Grow Up
How God's Word Produces Life, Love, and Maturity
There is something remarkable about watching a newborn grow. In the earliest days of life, an infant is entirely dependent, unable to do much of anything on its own. But within weeks, the baby begins holding its head up. Then sitting. Then smiling. Then walking, talking, reaching out to the world around them. Each milestone is a sign of something deeply right happening beneath the surface. And when growth is absent, concern follows. Doctors begin searching for what is wrong, because stagnation in a living thing is never a neutral condition.
The same principle applies to the spiritual life.
The apostle Peter draws on this very picture in 1 Peter 1:22-2:3, and the message is as relevant today as it was when he first wrote it. Believers have been born into God's family through the seed of His Word. Just as physical life begins with a seed and progresses toward maturity, spiritual life begins with the imperishable seed of Scripture and is meant to grow toward Christ-like love and holiness. The question worth sitting with is this: are we growing as God intended?
The Word of God Is Meant to Be Followed
Peter opens with a striking phrase: having purified your souls by your obedience to the truth. There is something that happens when we obey God's Word. It purifies. It sanctifies. It washes.
In John 17, Jesus prays over His disciples, asking the Father to sanctify them in the truth, and then He declares that God's Word is truth. This is not a casual observation. It is a declaration that shapes how we are to relate to Scripture. Every word in it is truth, and every word is there for a purpose.
James 1:18 reinforces this, describing how God brought us forth by the word of truth. The language is unmistakably that of birth. God issues spiritual life through His Word. Psalm 119:9 asks how a person can keep their way pure, and answers plainly: by guarding it according to God's Word.
This matters because walking outside of truth means walking in error. In a culture that celebrates personal truth and self-defined reality, God's people must be anchored to something that does not shift. God's truth does not change with the times.
The Word Produces Genuine Love
The goal of this purifying work is not merely behavioral modification. Peter tells us that the obedience to truth has a destination: sincere brotherly love. And then he calls believers even further, commanding them to love one another earnestly from a pure heart.
Here Peter moves between two different kinds of love. The first is a warm, brotherly affection, a genuine care for those in the community of faith. The second is agape love, the self-sacrificing, unconditional love that God Himself demonstrated toward us. Paul describes it in Romans 5:8 as Christ dying for us while we were still enemies. It was a decision of the will, entirely for the benefit of another, at great cost to Himself.
This is what believers are commanded to pursue toward one another.
1 Corinthians 13 gives this love its most detailed portrait. It is patient, which means it does not set deadlines for others to improve. It does not insist on its own way, which is a particular challenge for anyone who is convinced they are right. It bears all things and endures all things. These are not passive qualities. They are active, sustained choices rooted in the character of God working through His people.
Jesus Himself called this a new commandment in John 13:34-35, instructing His disciples to love one another as He had loved them, and declaring that this love would be the mark by which the world would recognize His followers. Not theological precision alone. Not years of church attendance. Love.
The fruit of the Spirit in Galatians 5:22-23 begins with love and then unfolds into joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. All of it flows from the same source: God's Word at work in a yielded life.
The Word Is Imperishable and Eternal
Peter grounds this entire discussion in the nature of the Word itself. He quotes from Isaiah 40:8, reminding his readers that all flesh is like grass and all its glory like the flower of grass. The grass withers. The flower falls. But the Word of the Lord remains forever.
Everything in human experience fades. Cultures shift. Empires collapse. Reputations dissolve. But God's Word stands. Jesus declares in Matthew 24:35 that heaven and earth will pass away, but His words will not. Isaiah 55 pictures God's Word like rain that falls from heaven and does not return empty, but accomplishes everything it was sent to do.
This is the seed that was planted in every believer at the moment of new birth. Not a perishable seed, but an imperishable one. The life it generates does not diminish over time. It is the living and abiding Word of God, described in Hebrews 4:12 as living, active, and sharper than any two-edged sword.
The Word Grows Us Toward Maturity
The final movement of this passage is a call to remove what hinders growth and cultivate a genuine hunger for the Word. Peter lists five relational toxins: malice, deceit, hypocrisy, envy, and slander. These are not minor inconveniences. They are weeds that choke spiritual development, drawing nutrients away from the life God is trying to grow.
In their place, Peter calls believers to long for the pure spiritual milk of the Word, using the image of a newborn crying out for nourishment. That intensity, that urgency, is the posture God is looking for. Not a casual glance at Scripture when convenient, but a deep craving rooted in the recognition that this is where life is found.
Psalm 34:8 captures it well, with its invitation to taste and see that the Lord is good. Once you have genuinely tasted, the appetite grows. And as that appetite is fed, growth follows.
The Word of God generates new life, produces genuine love, and matures those who receive it. The only question is whether we are positioning ourselves to receive it.
