Potter Helps a Child Shape the Clay
When someone believes in Jesus Christ and humbly responds with repentance, confession of sins, and submits to Him, the person will be transformed. The process is called sanctification. The word “sanctification” comes from the Greek word hagiasmos, which means to set aside or consecrate for the purpose of holiness. Philippians 2:12-13 tells us that sanctification is a cooperative effort. God is at work in us as we work out our salvation, that is, as we strive to be holy. The description is like a professional potter who works with an amateur to shape the clay into something wonderful. He helps us become more like Christ. The process is sanctification. Sanctification has three phases: positional sanctification, progressive sanctification, and ultimate or perfected sanctification.
Sanctification: Positional
Positional sanctification refers to a change in status before God at the moment of saving faith. When one believes in Jesus Christ, his or her sins are forgiven (Acts 10:43) and they are divinely and legally declared to be justified and righteous (Romans 5:1, 9). He or she is also made into a new creature (2 Cor. 5:17) and is now free for the first time in life to do good (Rom. 6:11, 14, 18). Ephesians 2:1-7 describes it like this,
And you were dead in your trespasses and sins, in which you formerly walked according to the course of this world, according to the prince of the power of the air, of the spirit that is now working in the sons of disobedience. Among them we too all formerly lived in the lusts of our flesh, indulging the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest. But God, being rich in mercy, because of His great love with which He loved us, even when we were dead in our transgressions, made us alive together with Christ (by grace you have been saved), and raised us up with Him, and seated us with Him in the heavenly places in Christ Jesus, so that in the ages to come He might show the surpassing riches of His grace in kindness toward us in Christ Jesus. Ephesians 2:1-7 (NASB)
That is, we were once spiritually dead; but now we are spiritually alive. Those who truly believe in God are considered and treated as if they are already seated in heaven. They have been declared by God to be legally holy and worthy of the new heaven and new earth.
Sanctification: Progressive
But in reality we still live in this present world and live in our present sinful bodies. We are sinners who still sin even though God considers us legally qualified to enter heaven as holy people. There is a war within ourselves between sin and righteousness. The war reveals that we are new creatures who are in conflict with the old sinful flesh. The apostle Paul mourned his own sin and tells us that he still struggled with his old self.
For what I am doing, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate . . . For I know that nothing good dwells in me, that is, in my flesh; for the willing is present in me, but the doing of the good is not. For the good that I want, I do not do, but I practice the very evil that I do not want. Rom. 7:15, 18-19 (NASB)
God knows that we still sin, but yet He treats us as pardoned criminals. Our sins have been pardoned. We are not on parole and there is no purgatory. Yet, everyone who believes in Jesus Christ and accepts Him as his or her Savior will suffer in this life for some of the sins that he or she commits. In response, God will motivate His followers to stop sinning through trials and difficult situations in this life. Trials in this life are unavoidable. That is the message of Hebrews 12:8.
But if you are without discipline, of which all have become partakers, then you are illegitimate children and not sons. Hebrews 12:8 (NASB)
This passage tells us that if we never experience divine discipline, if we never go though trials in this life, then we do not belong to Him. It will be a sign that one is not a true Christian. In 1 Corinthians 15:1-2, the apostle Paul warns us that one can act like a Christian or claim to believe in Jesus Christ and yet not be a real Christian. Hebrews 12:8 is another proof that one can use to determine if he or she is a Christian.
James 1:2-4 says that trials and tests are essential to a Christian’s spiritual maturity.
Consider it all joy, my brethren, when you encounter various trials, knowing that the testing of your faith produces endurance. And let endurance have its perfect result, so that you may be perfect and complete, lacking in nothing. James 1:2-4 (NASB)
Here we are encouraged not to flee from a difficult situation but to continue in the situation. (The Lord is not talking about physically dangerous situations.) Trials are essential for us to grow spiritually. The goal in the Christian life is to become holy like God (1 Peter 1:14-16) and to know Him (1 John 2:12-14).
Sanctification: Ultimate or Perfected
Some day everyone will leave this earth and become immortal. But only those who have believed in Jesus Christ and have willingly yielded themselves to Him will spend eternity with God. That is, only those who are forgiven and have been declared to be holy by God will be with Him for eternity. Only the holy can live with Him. Who are these people? The answer is those who have been forgiven because they believe in Jesus Christ. That is, positionaly, we are holy in His sight.
. . . and nothing unclean, and no one who practices abomination and lying, shall ever come into it, but only those whose names are written in the Lamb’s book of life. Revelation 21:27 (NASB)
Even though we are positionally holy before God, in practice we are still sinners and sanctification continues to perfect those of us who are believers.
Therefore, having these promises, beloved, let us cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God. 2 Corinthians 7:1 (NASB)
In practice, a Christian who hungers and thirsts after righteousness (Matthew 5:6) will become more and more like Jesus Christ. The process will continue until we die or are raptured and meet God.
Now may the God of peace Himself sanctify you entirely; and may your spirit and soul and body be preserved complete, without blame at the coming of our Lord Jesus Christ. 1 Thessalonians 5:23 (NASB)
Odds and Ends
Now to answer a few of your other questions. Sanctification is not a reward (1 Corinthians 10:24). It is included with the gift of saving faith in Jesus Christ (Ephesians 2:8-9). Next, if a person believes and accepts Jesus Christ and then dies immediately, only the initial step of sanctification will have occurred. Sanctification will have started. The person will have been declared to be legally holy and ready to meet God. Positionally, he or she will be holy. Third, Zechariah 13:9 is a future prophecy about the nation of Israel that has not yet been fulfilled and has nothing to do with sanctification.
Conclusion
Sanctification is a process that starts immediately at the moment a person truly believes in Jesus Christ. God urges you to participate in the process of sanctification. A Christian can accelerate the process of sanctification by the study of God’s Word (John 17:17; Acts 2:42; Hebrews 5:11-14; 2 Timothy 3:16-17), praying (1 Thessalonians 5:17), using one’s spiritual gifts (Ephesians 4:11-13), spending time with other believers (Hebrews 10:24-25), making disciples and being discipled (Hebrews 13:7), and pursuing holiness (1 Thessalonians 4:3-7). These are essential to the process of sanctification.
Pursue peace with all men, and the sanctification without which no one will see the Lord. Hebrews 12:14 (NASB)
