Isaiah 35:8: Pursue holiness today?
How does Isaiah 35:8 encourage us to pursue holiness in a secular world?

Setting the Scene

Isaiah 35 paints a picture of God’s promised restoration—a flourishing desert, the weak made strong, and finally “a highway” for redeemed people to travel. Verse 8 focuses that hope into a clear call for daily living in the present world.


The Text

“And there will be a highway called the Way of Holiness. The unclean will not travel it—only those who walk in that Way—and fools will not stray onto it.” (Isaiah 35:8)


Understanding “the Highway of Holiness”

• A real, prepared path—God Himself establishes the route; we do not decide where it goes.

• Marked by separation—“the unclean will not travel it,” underscoring moral distinction from the surrounding culture.

• Safe and straightforward—“fools will not stray onto it,” meaning the path is clear enough that even the simple, once redeemed, can follow without missing the way.

• Exclusively for the redeemed—verse 9 continues, “but only the redeemed will walk there.” The road is for those purchased by God’s grace.


What the Verse Says to Us Today

1. Holiness is not optional; it’s the only road available to God’s people. (Hebrews 12:14)

2. The path exists now, not merely in the future kingdom. We walk it amid secular society.

3. Purity is possible because God has paved the highway; He supplies direction and strength. (Ezekiel 36:27)


Practical Steps for Staying on the Way

• Guard what enters the heart. “How can a young man keep his way pure? By guarding it according to Your word.” (Psalm 119:9)

• Renew the mind daily. “Do not be conformed to this world, but be transformed by the renewing of your mind.” (Romans 12:2)

• Choose companions wisely. “Bad company corrupts good character.” (1 Corinthians 15:33)

• Practice immediate obedience. Small compromises are off-ramps; quick obedience keeps us centered on the path.

• Lean on the Spirit’s power. (Galatians 5:16)


Living Counter-Culturally

• Distinct speech—truthful, gracious, free from coarse joking. (Ephesians 4:29)

• Distinct ethics—integrity at work, honesty in finances.

• Distinct relationships—self-sacrificial love, sexual purity, covenant faithfulness. (1 Thessalonians 4:3-4)

• Distinct hope—confidence rooted in Christ’s return, not earthly success. (Titus 2:11-13)


Encouragement for the Journey

Isaiah’s promise reminds us that holiness is a journey already mapped out by God, not an impossible climb of our own invention. While the surrounding culture may wander aimlessly, we have a clear, God-built highway under our feet. Walking it means aligning thoughts, words, and actions with the character of the One who called us: “Be holy, because I am holy.” (1 Peter 1:15-16)
