Sanctified Past Tense

1 Cor 1:30 says Christ became for us wisdom from God, as well as righteousness, sanctification, and redemption. We usually think of growing in wisdom and righteousness, but of redemption being an all-at-once kind of thing. If you look at the context, Paul is talking about how God chose the foolish, the weak, the insignificant and the despised to shame the wise, strong, powerful and noble. So you could say that this is not a case of us BECOMING wise, but of God's wisdom in Christ working in us, and this is true from the moment of salvation, as is Christ BEING righteousness, sanctification, and redemption, not granting them.

In Chapter 6, verse 11, he says that some of the Corinthians were sexually immoral, idolaters, adulterers, male prostitutes, homosexuals, thieves, greedy people, drunkards, revilers, and swindlers, BUT they were: WASHED, SANCTIFIED, and JUSTIFIED. The implication is this: because of these three processes, they are not (or should not be?) any longer those bad things.

So in each of these cases, sanctification is an event in the past, with impact in the present. Christ became our sanctification, and remains so. We were sanctified, so our behavior can be (should be!) different than it used to be.
