"…I am the Lord who sanctifies you" (Exod. 31:13).
Sanctification in the Greek means “purification”, “to make holy”, and “to purify or consecrate.” Justification happens only once when we first get saved but sanctification is a lifetime process by which God conforms us “to the image of His Son” (Rom. 8:29). Though we are saved and justified after believing in the Lord Jesus yet the old nature and the old man still remains in us until “the redemption of our body” (Rom. 8:23). The old nature and the old man fights with the new nature and the new man so that we cry out like the Apostle Paul “O wretched man that I am! Who will deliver me from this body of death?”
SANCTIFICATION – GOD’S COMMAND & GOD’S WILL FOR YOU
"Therefore you shall be perfect, just as your Father in heaven is perfect" (Matt. 5:48).
"For this is the will of God, your sanctification: that you should abstain from sexual immorality; that each of you should know how to possess his own vessel in sanctification and honor" (1 Thess. 4:3-4).
"As obedient children, not conforming yourselves to the former lusts, as in your ignorance; but as He who called you is holy, you also be holy in all your conduct, because it is written, “Be holy, for I am holy”" (1 Peter 1:14-16).
HOW GOD SANCTIFIES US
By the Holy Spirit
"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 Thess. 2:13).
"Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God" (1 Cor. 6:9-11).
Through Jesus Christ
"But of Him you are in Christ Jesus, who became for us wisdom from God—and righteousness and sanctification and redemption" (1 Cor. 1:30).
"For both He who sanctifies and those who are being sanctified are all of one, for which reason He is not ashamed to call them brethren" (Heb. 2:11).
"By that will we have been sanctified through the offering of the body of Jesus Christ once for all" (Heb. 10:10).
"For by one offering He has perfected forever those who are being sanctified" (Heb. 10:14).
By the Word of God
"Sanctify them by Your truth. Your word is truth" (John 17:17).
"You are already clean because of the word which I have spoken to you" (John 15:3).
"Husbands, love your wives, just as 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, that He might present her to Himself a glorious church, not having spot or wrinkle or any such thing, but that she should be holy and without blemish" (Eph. 5:25-27).
