Several aspects of sanctification are important to Christians. The primary meaning, which occurs at the moment of our salvation, is the dedication, consecration, and setting apart of the Christian for the holy work of God. And the secondary meaning of sanctification is the cleansing and purging of all moral defilement, which is an ongoing, progressive experience for the believer. Lastly, the complete and final sanctification occurs when Jesus returns, and we are delivered from our old sinful nature into a resurrected eternal, incorruptible body.
