How to Keep Going When Growth Feels Slow

Sanctification takes time

Key Quote:
“Sanctification is the work of a lifetime.”
R. C. Sproul

Sanctification takes time, and that can be discouraging when you want change to happen faster than it does. Many believers become weary because they expect spiritual growth to feel more immediate, more visible, and more complete than it often does. When old struggles return, when progress feels small, or when patterns seem stubborn, it can be tempting to wonder whether anything is really changing at all.

But sanctification takes time because God is doing deep work, not shallow work. He is not merely improving outward habits. He is reshaping the heart.

Why Slow Growth Can Feel Discouraging

Slow growth tests our expectations. We want breakthroughs, quick victories, and obvious results. We want to see clear proof that we are becoming more mature. So when we still battle fear, pride, lust, anger, discouragement, selfishness, or spiritual dullness, we can begin to question whether grace is really at work. Yet, it is important to remember that the journey of sanctification requires patience, because significant change takes time.

That is one reason it matters to remember that sanctification takes time. Growth in holiness is often steady before it is dramatic. It is often quieter than we expected. It may show up in slower speech, deeper conviction, quicker repentance, gentler responses, and a growing awareness of our need for Christ. These changes may not always feel impressive, but they matter.

Biblical Perspective

Scripture never presents sanctification as instant perfection. The Christian life is a lifelong process of being conformed to the image of Christ. God works patiently, wisely, and purposefully in His people over time. He exposes sin, deepens repentance, strengthens faith, renews the mind, and teaches us to walk in obedience.

That means slow growth is not the same as no growth. Sometimes the very grief you feel over sin is evidence that God is at work in you. Sometimes the deeper awareness of your weakness is not proof of failure, but proof that the Lord is making you more honest and dependent. The fact that sanctification takes time helps us see the value in these gradual changes.

Sanctification takes time because the Lord loves His people enough to work deeply, not merely quickly.

Scripture for Today

“And I am sure of this, that He who began a good work in you will bring it to completion at the day of Jesus Christ.”
Philippians 1:6

This verse anchors the believer’s hope in God’s faithfulness, not in personal speed. The Lord began the work, and the Lord will complete the work. That does not excuse passivity, but it does remove despair. Your growth is not hanging by the thread of your own strength. It rests in the hands of the God who finishes what He starts, and we must remember that spiritual sanctification takes perseverance and time.

How Christ Meets Us Here

Our deepest problem is not simply that growth feels slow. It is that we are sinners who need more than gradual improvement. We need a Savior. Left to ourselves, we do not grow into holiness by effort alone. We need forgiveness for our sin, power for real change, and hope rooted outside ourselves. Surprisingly, sanctification takes time, but Christ provides both patience and progress along the way.

Jesus Christ came to save us completely. He lived the holy life we could never live, died for our sin, and rose again in victory. That means sanctification is not a process of earning God’s favor. It is the ongoing work of grace in those who already belong to Him through Christ.

Jesus does not merely command holiness from a distance. By His Spirit, He is actively forming His people. He intercedes for them, sustains them, corrects them, and changes them. When growth feels slow, Christ remains faithful. When progress feels hidden, Christ remains at work. He is not discouraged by the process, and He is not abandoning His people in it. Because sanctification takes time, we know He is patient and committed throughout the journey.

Bringing It Home

Ask yourself these questions today:

• Where have I been discouraged by slow growth?
• What change have I expected to happen faster than it has?
• Have I mistaken slow growth for no growth?
• How might God already be at work in ways I have not fully noticed? Sometimes, we overlook progress because sanctification takes time and rarely happens all at once.

Take time today to thank the Lord for even small evidences of grace. Thank Him for conviction, for repentance, for deeper honesty, for a growing hunger for His Word, or for any area where He is making you more like Christ. Then ask Him for patience to keep walking faithfully.

Prayer

Father, thank You that You are patient with Your people and faithful to finish the work You begin in them. Thank You for sending Your Son, the Lord Jesus Christ, whose righteousness covers me, whose death secures my forgiveness, and whose resurrection gives me living hope. By the power of Your Holy Spirit, keep me from discouragement when growth feels slow, strengthen me to keep walking in repentance and faith, and continue shaping me into the likeness of Christ. In Jesus’ name, amen. In all things, help me trust that sanctification takes time and requires Your guidance.
