Motivation is the key component when it comes to self-sanctification. Do we have a self-sanctification in the positive sense of separating ourselves from those things we know that are not good for us or not good for others, not in order to merit any more righteousness before God through that performance, but in light of all that God has already made us to be IN Christ (Our new identity). On the opposite end of that self-sanctification spectrum, we have those who suppose that their behavior is the source of their right standing with God, that is self-sanctification negatively. They suppose that becoming more righteous in practice will make them more righteous in God’s sight, faulty thinking on their part, Paul called it foolish. It will not gain them Heaven, it will not help them avoid the second death. Paul lets us know that in the book of Romans that God did not make Heaven for good people, God made Heaven for sinners who are justified freely by God’s grace. Paul did not set himself apart in order to gain a greater righteousness before God through his performance, but that he made his life-style (to the best he could) conform to who God had already made him to be in his sanctified or set-apart position being joined to Christ that he might more affectively reach others. That was Paul’s key motivation; there is a vast difference in those two motivations. Setting oneself apart for holiness is one thing, setting oneself apart because of the holy standing God has already given that individual in Christ is something altogether different.
