The Justification and Sanctification of believers through the finished work of Christ,

1 Timothy 1:15-16

New American Standard Bible (NASB)

15 It is a trustworthy statement, deserving full acceptance, that Christ Jesus came into the world to save sinners, among whom I am foremost of all. 16 Yet for this reason I found mercy, so that in me as the foremost, Jesus Christ might demonstrate His perfect patience as an example for those [a]who would believe in Him for eternal life.

The Justification and Sanctification of believers through the finished work of Christ, recently we briefly examined the important doctrine of Justification, which in many ways is part of the bigger picture of Salvation and the Christian life and walk, today we will examine briefly the important doctrine of Sanctification which follows on from Justification.

1)   Now let us look at the differences between Justification and Sanctification

Justification	Sanctification
Legal Standing	Internal Condition
Once for all time	Continuous throughout life
Entirely God’s work	We co-operate with God
Perfect in this life	Not perfect in this life
The same in all Christians	Greater in some than in others

Sanctification differs from justification in several ways. Justification is a one-time work of God, resulting in a declaration of “not guilty” before Him because of the work of Christ on the cross. Sanctification is a process, beginning with justification and continuing throughout life. Justification is the starting point of the line that represents one’s Christian life; sanctification is the line itself

2)   Sanctification is a progressive work of God and man that makes us more and more free from sin and like Christ in our actual lives

 Sanctification is the process of renewal and consecration by which believers are made holy through the work of the Holy Spirit. Sanctification is the consequence of justification and is dependent upon a person being in a right relationship with God.

Sanctification is applied justification. By its very nature justification does not have a progressive character. It is God's declaration of righteousness. The focus of justification is the removal of the guilt of sin. The focus of sanctification is the healing of the dysfunctionality of sin. Since all spiritual blessings, justification and sanctification included, are the Christian's the moment he or she is "in Christ" sanctification is total and final in one sense Yet, unlike justification, sanctification also continues until it will be consummated when Jesus Christ returns. For then we will be like him, perfect and complete. Sanctification, therefore, has an initial, progressive, and final phase. A believer's present preoccupation is with progressive sanctification, by which the child of God lives out the implications of initial sanctification with an eye to the goal of final sanctification. The sanctified life is victorious, though it is lived out in the context of temptation and suffering. God promises the "overcomers" in Revelation 2 and 3 to restore all that was lost in the fall, in sanctification; the believer is simply applying the implications of his or her justification.

3)   A believer grows in sanctification by living according to his or her new identity

 Sanctification, defined broadly as the work of God’s grace in man’s perfection in righteousness, begins when he becomes a believer and hence is “in Christ.” It continues progressively until death brings him into Christ’s presence unless he “does despite to the Spirit of grace.” It is only as one by dedication and faith realizes in actuality what is provided in the atonement that this grace is experienced; it does not follow as a matter of course, as the exhortations in the NT imply. Parallel to the work of sanctification is the infilling of the Holy Spirit in the believer, perfection in love, having the “mind of Christ,” and “walking as he walked.”

There are many things that I can say about Sanctification but more importantly that I what I can stay about Sanctification is what the Bible says about Sanctification.  

Now let us look at some scriptures in regards to Sanctification

1)   Romans 6:15-19 15 What then? Shall we sin because we are not under law but under grace? May it never be! 16 Do you not know that when you present yourselves to someone as slaves for obedience, you are slaves of the one whom you obey, either of sin [j]resulting in death, or of obedience [k]resulting in righteousness? 17 But thanks are to God that [l]though you were slaves of sin, you became obedient from the heart to that form of teaching to which you were committed, 18 and having been freed from sin, you became slaves of righteousness. 19 I am speaking in human terms because of the weakness of your flesh. For just as you presented your members as slaves to impurity and to lawlessness, [m]resulting in further lawlessness, so now present your members as slaves to righteousness, [n]resulting in sanctification.

2)   1 Corinthians 1:30 30 But [u]by His doing you are in Christ Jesus, who became to us wisdom from God, [v]and righteousness and sanctification, and redemption.

3)   I Thessalonians 5:23-24 23 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. 24 Faithful is He who calls you, and He also will bring it to pass.

4)   I Thessalonians 4:1-8 4 finally then, brethren, we request and exhort you in the Lord Jesus, that as you received from us instruction as to how you ought to [a]walk and please God (just as you actually do [b]walk), that you excel still more. 2 For you know what commandments we gave you [c]by the authority of the Lord Jesus. 3 For this is the will of God, your sanctification; that is, that you abstain from [d]sexual immorality; 4 that each of you know how to [e]possess his own [f]vessel in sanctification and honour, 5 not in [g]lustful passion, like the Gentiles who do not know God; 6 and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you. 7 For God has not called us for the purpose of impurity, but [h]in sanctification. 8 So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you

5)   2 Thessalonians 2:13-17 13 But we should always give thanks to God for you, brethren beloved by the Lord, because God has chosen you [o]from the beginning for salvation [p]through sanctification [q]by the Spirit and faith in the truth. 14 It was for this He called you through our gospel, [r]that you may gain the glory of our Lord Jesus Christ. 15 So then, brethren, stand firm and hold to the traditions which you were taught, whether by word of mouth or by letter [s]from us.16 Now may our Lord Jesus Christ Himself and God our Father, who has loved us and given us eternal comfort and good hope by grace, 17 comfort and strengthen your hearts in every good work and word.
