Explain the difference between Justification and Sanctification

 Two views in the seemingly eternal question about Eternal Security are the Arminian who denies that “the true child of God is eternally secure” while the Calvinist “insists that, if he does not persevere in holiness, he was never regenerate in the first place.” With thanks to CM who further adds; “Can a man lose his salvation? Yes, if it depends on him; our eternal security is a gift of mercy through faith.
 
The simple message of the Gospel is provided by Paul in 1 Corinthians 15:3-4, “For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:"

CM puts the cookies on the bottom shelve; “The problem is the difference between justification (entrance) and sanctification (for inheritance).” Add to that is his summation of The Tenses of “Salvation”

Past Tense: Separation from the Penalty of Sin Justification
Present Tense: Separation from the Power of Sin Sanctification
Future Tense: Separation from the Presence of Sin Glorification

Here I’m concerned with the past and present tenses only and remember the lesson concerning tenses:

As past perfect means having been competed or passive voice where the subject receives the action (Justification) would imply that it is something that is done is for us (sinners). I would compare the present tense or currently continuing to the middle voice where there is an interaction of sorts between us and the Holy Spirit, something that is in us (Sanctification) that makes us (sinners) righteous.

Justification declares the sinner righteous and assures the believer of his/her entrance into heaven. Sanctification makes the sinner righteous.

Paul often spoke about justification by faith, Galatians 2:16, “Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.”

Ask most people who call themselves Christians if they think they're going to Heaven and often the answer will be something like, “Oh yes I'm a good person” and they will continue to bloviate about all their good works. When I mention that our salvation or justification is a gift given to us free of charge through faith in the work of Jesus Christ on the cross usually I get “that look.”

As for good works, these should follow from the individual being justified. If one is truly a follower of Jesus, it is expected that really sinful behavior would no longer appeal to him or her. Also doing good works should follow such as supporting pro-life groups, Israel or perhaps blogging.
