What are believers being sanctified from according to 2 Corinthians 7:1?

The concept of sanctification in 2 Corinthians 7:1 refers to the process of believers being set apart for God's purposes and being made holy. In this context, the passage emphasizes the need for believers to cleanse themselves from all filthiness of the flesh and spirit. The reference to 'flesh and spirit' highlights the dual aspects of human nature that can hinder spiritual growth and relationship with God.

Sanctification involves not only moral and ethical behavior (associated with the flesh) but also the attitudes and intentions of the mind and soul (related to the spirit). It calls believers to actively pursue holiness by removing anything that could contaminate their relationship with God. The focus on both the flesh and the spirit underscores a holistic approach to living a life that is pleasing to God.

This understanding captures the essence of the sanctifying process, stressing the importance of addressing both the external actions and internal motivations of a believer.
