What We Believe: Sanctification 6/21/2026 PM

Sanctification is what happens next in the life of every true believer. Salvation is not the point where a person is saved and then does nothing about it. Salvation is the point where a person begins wanting to be more like Jesus, begins wanting to make changes, and begins showing that God has truly done a work in the heart.

Sanctification means being set apart. God sets his people apart from the world and to himself, so their lives, purposes, conduct, and goals are different. The doctrine has both a positional and a progressive side. Positional sanctification happens at salvation, because God declares the believer righteous in Christ and sees Christ’s holiness rather than sin. Progressive sanctification begins there and continues through the whole Christian life, because the believer has not yet become in practice all that God has declared him to be in position.

First Thessalonians says plainly that God’s will is sanctification. God calls his people to control their bodies in holiness and honor, not like those who do not know God. Second Corinthians 7 ties cleansing and perfecting holiness to the promises of God, because God has welcomed his people and made them sons and daughters. Ephesians 1 shows that God chose his people so that they should be holy and blameless before him, so holiness is not an optional add-on after salvation.

Progressive sanctification means growth, but that growth is not always a clean upward line. Hebrews calls believers to go on to maturity. Second Peter calls faith to be supplemented with virtue, knowledge, self-control, steadfastness, godliness, brotherly affection, and love. Those qualities keep a person from being ineffective and unfruitful, and their presence confirms calling and election. A lack of them makes a person nearsighted and blind, forgetting the cleansing already received.

Paul’s words in Philippians 3 show that maturity is not thinking a person has arrived. Maturity sees how much growth is still needed. Paul says he has not already obtained it, but presses on because Christ Jesus has made him his own. Sanctification is messy because the flesh remains. It can look like two steps forward and one step back, or sometimes one forward and two back, but God does not run away, hide, or leave.

Regeneration is where sanctification begins. No true righteousness happens before the new birth. Moral reform before salvation may look good, and it may help life here, but apart from Christ it is empty for eternity. Good man routines, better habits, and outward change cannot make anyone holy. True sanctification comes through Jesus, by the Spirit, from the work God begins in salvation.

Key Takeaways

• 1. Sanctification starts at real salvation Sanctification is not a second life added onto Christianity later. Sanctification begins where God gives life, because a true believer starts wanting Christlikeness instead of merely religious appearance. The saved person is set apart positionally, but that standing begins a real pursuit of holiness in daily life. [01:17]
• 2. Holiness is God’s stated will God does not leave holiness as a vague preference or a personality type for serious Christians. First Thessalonians says God’s will is sanctification, including bodily obedience, honor, and separation from the old Gentile way of not knowing God. The call to holiness rests on who God is and on what God has made his people to be. [06:41]
• 3. Maturity knows it has not arrived Paul’s mature mindset is not confidence that everything is settled, but honesty that growth is still needed. The mature person sees more clearly how far Christlikeness still reaches, and therefore presses on rather than coasting. Spiritual maturity is often measured by a deeper awareness of need, not by a louder claim of completion. [23:22]
• 4. Growth is real but messy Progressive sanctification does not always look like a straight line upward. The flesh remains, so there are falls, recoveries, slow seasons, and painful lessons where God brings his child close again. The messiness does not cancel the progress, but it does expose the need for confession, dependence, and continued pursuit. [26:21]
• 5. Moral reform cannot replace regeneration Good habits before salvation can look impressive, but they do not make a person holy before God. Apart from Christ, even morally upright choices remain empty for eternity because the heart has not been made new. Regeneration must come first, because true righteousness comes through Jesus and not through the “good man” routine.

1. According to 1 Thessalonians 4:3-5, what two aspects of sanctification does Paul emphasize (e.g., actions to avoid and positive behaviors to pursue)?
2. In Philippians 3:12-14, how does Paul describe his mindset about spiritual growth despite his maturity? [23:22]
3. What qualities does 2 Peter 1:5-7 list as essential to add to faith, and what purpose do they serve (v. 8)?

1. Why does Paul stress that he has “not already obtained” perfection in Philippians 3:12-14, even though he is a mature believer? How does this challenge common assumptions about spiritual maturity?
2. 1 Thessalonians 4:3 states that holiness is God’s “will.” What does this imply about the relationship between salvation and daily obedience? [06:41]
3. How do the qualities listed in 2 Peter 1:5-7 guard against being “ineffective or unfruitful” (v. 8)? What might “ineffective” faith look like practically?

1. Reflect on an area of your life where you feel “stuck” in growth (e.g., a recurring sin or stagnant habit). How does Paul’s example of “pressing on” in Philippians 3:12-14 encourage you to respond? [26:21]
2. The sermon mentioned that growth is often “messy” and not a straight line. Share a recent experience where your progress felt like “two steps forward, one step back.” How did you see God’s faithfulness in that season?
3. 2 Peter 1:5-7 calls believers to actively “supplement” faith with specific qualities. Which of these qualities (e.g., self-control, brotherly affection) do you find most challenging to pursue? What practical step could you take this week to grow in that area?
4. The sermon warned against relying on “moral reform” without regeneration. [36:30] How can you discern whether your efforts to change are rooted in Christ’s power or self-reliance?
5. 1 Thessalonians 4:3-5 urges believers to live distinctly from “the Gentiles who do not know God.” What is one way your daily choices (e.g., speech, entertainment, relationships) could better reflect being “set apart” for God?
6. When facing failure or slow growth, how might you practice “confession and dependence” (as mentioned in the sermon) instead of shame or giving up? [26:21]
