"Sanctification by the Holy Spirit"

1 O foolish Galatians! Who has bewitched you? It was before your eyes that Jesus Christ was publicly portrayed as crucified. 2 Let me ask you only this: Did you receive the Spirit by works of the law or by hearing with faith? 3 Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? 4 Did you suffer  so many things in vain—if indeed it was in vain? 5 Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith— 6 just as Abraham “believed God, and it was counted to him as righteousness”?
- Galatians 3:1-6 (ESV)

1. Sanctification is a work of the Holy Spirit

3 Are you so foolish? After beginning by means of the Spirit, are you now trying to finish by means of the flesh?
- Galatians 3:3 (ESV)
9 Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, 10 nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God. 11 And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
- 1 Corinthians 6:9-11

2. The Holy Spirit makes us more like Christ through Sanctification

5 For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit. 6 For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace.
- Romans 8:5-6 (ESV)
17 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 18 And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.
- 2 Corinthians 3:17-18
“Sanctification is by no means a mystical experience in which holiness is ours effortlessly. God gives increase in holiness by engaging our minds, wills, emotions, and actions. We are involved in the process. That is why biblical teaching on
sanctification appears in both the indicative (‘I the Lord sanctify you’) and the imperative (‘sanctify yourselves this day’).”
