By sanctification is ordinarily meant that hallowing of the Christian believer by which he is freed from sin and enabled to realize the will of God in his life.
THE THEOLOGY OF PAUL: Stand Firm
The Christians in Thessalonica were urged to adhere to what they had been taught. This passage can furnish no authority for holding the teachings which have come down from church leaders. No one should ever refer to themselves as a Calvinist, an Arminian, a Lutheran, a Wesleyan, and so on. You're either a Christian or you are not.
What Does the Bible Really Say About Salvation?
A price paid to buy back or to bring about a release from some obligation or undesirable circumstance. A ransom is a sum of money or a price demanded or paid to secure the freedom of an enslaved person. The basic idea of “ransom” is saving somebody from an oppressed condition or dangerous situation through self-sacrifice, such as a price that covers or satisfies justice. At the same time, the term “redemption” is the deliverance that results from the ransom.
