Hello, mikeledes…I have to admit, these are very in-depth questions and I am sure that I cannot answer from scripture in its entirety but I will take a crack at this…
- What is sanctification?
This has many meanings - in one sense it is an event, and another it is a process. It basically means “set-apart” I believe.
Heb 13:12 Therefore Jesus also, that He might sanctify the people through His own blood, suffered outside the gate.
Eph 2:13 But now in Christ Jesus you who formerly were far off have been brought near by the blood of Christ.
1Co 6:11 Such were some of you; but you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus Christ and in the Spirit of our God.
Also, this is the process by which we are made more and more like Christ by the inner working of the Holy Spirit and feeding on the Word of God.
1Th 4:3 For this is the will of God, your sanctification; that is, that you abstain from sexual immorality;
Heb 9:14 how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?
1Pe 1:1 Peter, an apostle of Jesus Christ, To those who reside as aliens, scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia, who are chosen
2 according to the foreknowledge of God the Father, by the sanctifying work of the Spirit, to obey Jesus Christ and be sprinkled with His blood: May grace and peace be yours in the fullest measure.
It is a gradual cleansing which I have certainly experienced over the past 8 years or so.
Again, you ask a very loaded set of questions. I usually like to respond with very thorough answers but that will take hours and space.
- How is it accomplished?
Through the Word of God as shown in scripture above and by the power of the Spirit and by the blood of Christ. It happens at the rebirth (those who are born of God are set apart by the blood of Christ) and throughout the life of a Christian.
- Is it a process? Yes and no - see above.
- What role do good works play?
Good works are an outflowing of God’s work in and through us and these works perfect our faith. Good works are brought forth as we were created unto good works.
Eph 2:10 For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them.
Php 2:13 for it is God who is at work in you, both to will and to work for His good pleasure.
Then there is Justification - which means to be declared righteous. I won’t get into that now.
It is all of God and by His grace.
