1 Thess. 4:3: God's will for sanctification?
How does 1 Thessalonians 4:3 define God's will for our sanctification?

Setting the Scene

Paul writes 1 Thessalonians to believers eager to grow. After commending their faith (4:1–2), he pinpoints exactly what pleases God.


The Core Statement: 1 Thessalonians 4:3

“For this is the will of God, your sanctification: that you abstain from sexual immorality.”

• God’s will is not vague—He states it plainly.

• “Your sanctification” places the emphasis on every believer, not a select few.

• The first arena Paul names is sexual purity: “that you abstain from sexual immorality.”


What Sanctification Means

• “Sanctification” (hagiasmos) = being set apart for God’s exclusive use.

• Two sides:

– Positional: God declares us holy in Christ (Hebrews 10:10).

– Progressive: the ongoing work of becoming like Christ (2 Corinthians 3:18).

• Here Paul stresses the progressive side—daily choices that match our holy calling.


Why Sexual Purity Takes Center Stage

• Sexual immorality (porneia) covers any sexual activity outside the covenant of marriage (Matthew 19:4–6; Hebrews 13:4).

• Our bodies are God’s temple (1 Corinthians 6:18-20).

• Purity protects fellowship with God and witnesses to the watching world (Ephesians 5:3-8).


Scripture Echoes That Reinforce the Point

1 Corinthians 6:18 – “Flee from sexual immorality.”

Ephesians 5:3 – “Among you there must not be even a hint of sexual immorality.”

Hebrews 12:14 – “Pursue holiness, without which no one will see the Lord.”

Romans 12:1-2 – Offer bodies as living sacrifices, “holy and pleasing to God.”


Practical Ways to Walk in Sanctification

• Flee, don’t flirt, with temptation (2 Timothy 2:22).

• Guard the mind—what we watch or click shapes desires (Philippians 4:8).

• Cultivate accountability with trusted believers (Galatians 6:1-2).

• Regularly renew commitments through Scripture and obedience (Psalm 119:9-11).

• Depend on the Spirit’s power; sanctification is His ongoing work (Galatians 5:16-25).


The Promise and Motivation

• God’s commands come with grace: “Faithful is He who calls you, and He will also do it” (1 Thessalonians 5:24).

• Pursuing purity is not merely avoiding sin; it is stepping into the joyful purpose for which God saved us—lives that shine His holiness in a dark world.
