Is sanctification a progressive process for Christians?

According to the sovereign grace perspective, sanctification is not viewed as a progressive process but as a completed work done by Jesus Christ. Hebrews 10:14 supports this when it declares that Christ's one offering has perfected forever those who are sanctified. This means that believers are fully set apart and made holy at the moment of faith in Christ's sacrificial work. While Christians will continue to grow in grace and understanding, the foundational act of sanctification is complete and not subject to ongoing improvement by human effort.
