Renewing the Mind to Think Like Christ

Sermon by Pastor Peter Lui

Continuing the series on building healthy foundations for Christian living, Pastor Peter Lui reminds the church that lasting spiritual growth begins with the mind. While many people focus on changing outward behaviour, God desires something far deeper—a transformed mind that thinks, discerns, and responds like Christ.

Drawing from Romans 12:2, together with Philippians 2:5 and 1 Corinthians 2:16, Pastor Peter emphasises that God is not interested in superficial change. Instead, He works from the inside out, renewing our minds so that our entire lives reflect the character of Jesus.

The Mind Is the Battlefield

The sermon begins by explaining the important role of the mind.

Our minds are where we think, reason, imagine, evaluate truth, and make decisions. They shape our attitudes, values, priorities, and worldview.

Because of this, the mind becomes one of Satan’s primary targets. Just as he planted doubt in Eve’s mind in the Garden of Eden, he continues to influence people through worldly philosophies, distorted values, and subtle deception.

Pastor Peter reminds us that if the mind is left unchecked, worldly thinking will eventually shape worldly living.

As Proverbs teaches:

“As a man thinks in his heart, so is he.”

Whatever controls our minds will ultimately influence our words, choices, and actions.

Do Not Be Conformed to the World

Paul’s first instruction is a negative command:

“Do not be conformed to this world.”

To be conformed means allowing ourselves to be pressed into the world’s mould.

Every day, society encourages believers to adopt values that contradict God’s Word. Christians who refuse to compromise are often labelled as outdated, narrow-minded, or irrelevant.

Yet Pastor Peter reminds us that followers of Christ are called to live differently. Whether in our speech, integrity, priorities, or relationships, our lives should clearly reflect Christ.

The world may never read the Bible—but it is constantly reading our lives.

Be Transformed

Paul’s second instruction is positive:

“Be transformed.”

The Greek word describes the same kind of transformation seen in a caterpillar becoming a butterfly.

This is not simply an external improvement but a complete inward transformation of character.

Pastor Peter explains that transformation is God’s work, not ours. Our role is to willingly surrender ourselves to Him, allowing the Holy Spirit to reshape us day by day.

Christian maturity is therefore not a one-time event but a lifelong process of becoming more like Christ.

Renewing the Mind

Transformation happens through the renewing of the mind.

Pastor Peter uses the illustration of renovating a house.

When a home is renovated, the structure remains, but the unwanted things are removed and replaced with what is new and beneficial.

Likewise, God does not discard our minds. Instead, He removes worldly thinking and replaces it with His truth.

The sermon highlights three primary ways God renews our minds:

Through God’s Word

Scripture teaches, corrects, equips, and transforms us.

God’s Word is living, active, and powerful. It exposes wrong thinking, shapes godly character, and provides wisdom for every area of life.

Pastor Peter encourages believers to allow Scripture—not culture or popular opinion—to become the foundation for every decision.

Through the Holy Spirit

The Holy Spirit reveals God’s wisdom and enables believers to understand spiritual truth.

While human wisdom has its limits, the Holy Spirit gives us what Scripture calls “the mind of Christ.”

As we walk closely with Him, our thinking becomes increasingly aligned with God’s perspective rather than the world’s.

Through Prayer

Prayer is another means by which God renews our minds.

As we pray under the guidance of the Holy Spirit, our desires, attitudes, and priorities become increasingly aligned with God’s will.

Prayer changes not only our circumstances but also our thinking.

Discovering God’s Will

The purpose of a renewed mind is not simply greater knowledge.

It is so that we may discern and embrace God’s will.

Romans 12 describes God’s will as:

• Good – Always beneficial and never harmful, even when it is challenging.
• Acceptable – Something we learn to embrace joyfully as we trust God’s wisdom.
• Perfect – Complete, mature, and leading us toward God’s intended purpose.

A renewed mind does not merely recognize God’s will—it delights in following it.

Like Jesus Himself, believers grow to say:

“I delight to do Your will.”

Thinking Like Christ

Pastor Peter concludes by pointing to the ultimate example—Jesus Christ.

Though fully God, Jesus humbled Himself, became a servant, and willingly obeyed the Father, even to the point of death on the cross.

Having the mind of Christ means learning to think as He thought:

• Choosing humility over pride.
• Serving rather than seeking recognition.
• Trusting God’s wisdom above human understanding.
• Valuing others above ourselves.
• Delighting in God’s will above personal preference.

The sermon closes with a practical challenge:

What is the default setting of your mind?

When faced with difficult decisions, do you instinctively turn to social media, popular opinion, or worldly advice—or do you first seek God’s Word?

God desires to continually renew our minds so that every thought, decision, and action reflects the heart of Christ.

As we allow the Holy Spirit to transform our thinking through Scripture and prayer, we become people who not only know God’s will but also joyfully live it.

May we daily put on the mind of Christ and be transformed from the inside out, bringing glory to God in every area of our lives.
