Why is complete sanctification important for Christians?

Complete sanctification is addressed in Hebrews 10:10, where it states that we are sanctified through the offering of the body of Jesus Christ once for all. This theological perspective highlights that sanctification is not merely a process but a positional reality for believers in Christ. Being sanctified means that we have been set apart for God's service and declared holy through Christ’s one-time sacrifice. This is significant for Christians as it reflects our identity in Christ and calls us to live out this sanctification in practical terms. While we struggle with sin in our lives, our standing before God is secure in Christ, who enables us to pursue holiness in our daily lives.
