Hebrews 12:9–10 Furthermore, we have had human fathers who corrected us, and we paid them respect. Shall we not much more readily be in subjection to the Father of spirits and live? For they indeed for a few days chastened us as seemed best to them, but He [God] for our profit, that we may be partakers of His holiness.

Hebrews 12:14 Pursue peace with all people, and holiness, without which no one will see the Lord.”

1 Thessalonians 4:3 For this is the will of God, Your sanctification:

1. The Holy Spirit

2 Thessalonians 2:13 But we are bound to give thanks to God always for you, brethren beloved by the Lord, because God from the beginning chose you for salvation through sanctification by the Spirit and belief in the truth. 

2. The Word

Ephesians 5:25–26 Christ also loved the church and gave Himself for her, that He might sanctify and cleanse her with the washing of water by the word

John 17:17 Sanctify them by Your truth. Your word is truth.

Romans 12:2 Be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God

Ephesians 4: 23 Be renewed in the spirit of your mind 

3. Faith

Acts 26:18 To open their eyes, in order to turn them from darkness to light, and from the power of Satan to God, that they may receive forgiveness of sins and an inheritance among those who are sanctified by faith in Me.

Romans 10:17 Faith comes by hearing, and hearing by the word of God

The more we give heed to God’s Word, the more our faith expands, enabling us to appropriate the total provision God has made for our holiness.

4. The Blood of Jesus

Hebrews 13:12 Therefore Jesus also, that He might sanctify the people with His own blood, suffered outside the gate.

1 John 1:7 If we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin

1 John 5:18 We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him

1 John 3:9 Whoever has been born of God does not sin, for His seed remains in him; and he cannot sin, because he has been born of God.

5. The Altar

Matthew 23:16–17 Woe to you, blind guides, who say, ‘Whoever swears by the temple, it is nothing; but whoever swears by the gold of the temple, he is obliged to perform it.’ Fools and blind! For which is greater, the gold or the temple that sanctifies the gold?

Jesus is saying that the gold is not holy in itself; it is just metal. But when it is built into God’s temple it becomes holy. The temple makes it holy.

Matthew 23:18-19 And, whoever swears by the altar, it is nothing; but whoever swears by the gift that is on it, he is obliged to perform it.’ Fools and blind! For which is greater, the gift or the altar that sanctifies the gift?

Romans 12:1 I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.

Romans 12:2 And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
