2 Corinthians 7:1 Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
We are ambassadors for Christ by God’s grace who have been entrusted with the word and ministry of reconciliation to reconcile unsaved people to God 2 Corinthians 5:17-21. As workers together with God this grace we have received would be in vain if we do not also walk in holiness. Living holy allows Him to use us in unlimited ways to reach our generation with the Gospel. Holiness is a provision of grace whereby the righteous and holy nature of our new creation spirit makes possible a walk in the spirit above the lusts of the flesh. It has been created in righteousness and true holiness (Ephesians 4:24).
We often associate unholy things with works of the flesh or deeds only (Galatians 5:19-21). Bad attitudes can be unholy things too but not so obvious as works of the flesh. Second Corinthians 6 deals with separation from unholy things and concludes with a statement in 2 Corinthians 7:1 that says, “Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.” Filthiness of the spirit can include things that need cleansed in the spirit of your mind not things in your spirit man (because it’s been created in righteousness and holiness Ephesians 4:23, 24). This can be bad attitudes that need cleansed. An attitude is a predisposition or tendency that evaluates and responds positively or negatively toward certain ideas, objects, people, or situations. The attitude causes us to evaluate something by how we previously felt about it and bringing that feeling into our present behavior toward it. The attitude can be totally wrong and it will cut you off. It needs purged from our soul.
You can have all the right associations and a defiled attitude can cut you off.
Think about Judas who was in the company of Jesus and the other disciples.
Think about Gehazi who was Elisha’s servant who could have received his mantle.
Think about Ananias and Saphira who were associated with the outpouring of the Spirit on Pentecost.
Think about Lucifer, who originally was in the very presence of God.
All missed it and messed up because of a filthy attitude. Perfecting holiness involves not just cleaning up the outside of our life but also the inside by allowing God’s implanted word to remove filthiness from within our soul James 1:21. Our soul (mind, will, and emotions) isn’t instantly saved at salvation but under goes a process of salvation where the parts of our soul still influenced by the sinful fleshly nature need dealt with. The victory has already been won by Jesus and the provision for us to apply it is already ours in Christ by the grace of God. What remains is our responsibility to cleanse or purge ourselves from it.
