Why We Must Walk in the Truth
Base Text: Philippians 3:15–16 "Therefore let us, as many as are mature, have this mind; and if in anything you think otherwise, God will reveal even this to you. Nevertheless, to the degree that we have already attained, let us walk by the same rule, let us be of the same mind."
INTRODUCTION
The Prayer for Unity The heart of our Lord Jesus has always beat for the unity of His people. In His high priestly prayer, He asked that we might be one, just as He and the Father are one, so that the world might believe (John 17:20–23). The Apostle Paul echoed this, pleading that there be no divisions among us (1 Corinthians 1:10).
The Source of Division Why, then, is there so much religious division? It arises when man rejects the absolute authority of God's Word and replaces it with:
• Human Creeds: Teaching as doctrines the commandments of men (Mark 7:6–7).
• Human Traditions: Setting aside God's law to keep our own customs (Mark 7:8–9; Colossians 2:8).
• Human Reasoning: Relying on our own sight rather than walking by faith (2 Corinthians 5:7).
The Bible warns that the way that seems right to a man leads only to death (Proverbs 14:12). Instead, God finds no greater joy than seeing His children walk in the truth (2 John 4; 3 John 3–4).
Proposition: To walk in the truth is to believe it, confess it, practice it, and rejoice in it.
I. WE MUST WALK BELIEVING GOD'S TRUTH
You cannot walk in a truth you do not fully trust.
• Confidence in the Message: We must be convinced that the Word is faithful and worthy of all acceptance (1 Timothy 1:15; 4:9). We believe that Christ’s mission was to save sinners (Luke 19:10) and that even the "chief of sinners," like Paul, can find mercy as a pattern for us all (1 Timothy 1:16).
• Absolute Authority: God’s Word is not a collection of opinions; it is Truth itself (John 17:17). Though scoffers may doubt His promises or the timing of His return, we believe that God is not slack, but patient, wanting all to reach repentance (2 Peter 3:3–4, 9).
• The Rule of Truth: Walking demands a "rule" or a standard. This requires us to receive the Word not as the word of men, but as the divine power that works effectively in those who believe (1 Thessalonians 2:13; 2 Timothy 1:12).
II. WE MUST WALK IN THE PROFESSION OF GOD'S TRUTH
Walking in the truth involves a public alignment with Christ.
• The Good Confession: We are called to "lay hold on eternal life" by confessing our faith before many witnesses (1 Timothy 6:12). We must hold fast to the profession of our hope without wavering (Hebrews 10:23).
• Without Shame: Jesus warned that if we are ashamed of Him and His words in this generation, He will be ashamed of us when He returns in glory (Luke 9:26). We must not be like the rulers who believed but refused to confess Him because they loved the praise of men more than the praise of God (John 12:42).
• A Living Profession: Our confession is not just verbal; it is a lifestyle. We let our light shine through good works (Matthew 5:16) and do everything—in word or deed—in the name of the Lord Jesus (Colossians 3:17).
III. WE MUST WALK IN THE PRACTICE OF GOD'S TRUTH
Truth is meant to be lived, not just studied. It must move from the head to the heart and finally to the hands.
• Faith in Action: We are commanded not to love in word or tongue only, but in "deed and in truth" (1 John 3:18–19). A faith that does not result in works is a dead faith (Santiago 2:14–22).
• Adorning the Doctrine: Our behavior should "adorn" the doctrine of God our Savior (Tito 2:10). When we put on mercies, kindness, and humbleness, we make the truth beautiful to those watching (Colossians 3:12).
• The Fruit of Truth: A tree is known by its fruit. The power of the truth is confirmed when our daily conduct reflects the character of Christ (Matthew 7:16–18).
IV. WE MUST WALK IN THE JOY OF GOD'S TRUTH
Finally, walking in the truth is not a heavy burden; it is a source of profound joy.
• The Rejoicing of the Saved: When the Ethiopian eunuch heard the truth and was baptized, he went on his way rejoicing (Acts 8:39). The Gospel is inherently "Good News."
• Strength in Trials: The truth sustains us when life gets hard. Because we are justified by faith, we have peace with God and can even glory in tribulations, knowing they produce character and hope (Romans 5:1–5). Though we may be hard-pressed, we are not crushed, because the truth of our eternal weight of glory outweighs our light afflictions (2 Corinthians 4:8–11, 17).
• The Power of Liberty: The greatest joy of the truth is its liberating power. Jesus promised: "And you shall know the truth, and the truth shall make you free" (John 8:32). Free from guilt, free from the power of sin, and free to serve God.
CONCLUSION
To walk in the truth is to align every part of our existence—our mind, our mouth, our hands, and our heart—with the Word of God. The truth is the only path that leads to unity, the only profession that offers hope, the only practice that produces fruit, and the only joy that never fades.
Are you walking by the "same rule" today?
