... being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ. Philippians 1:6: (NKJV) Paul reminds us in his letter to the Thessalonians that we are a three part being, spirit, soul and body. We live so much each day by the thoughts of our soul and the actions of our body, we forget we are also a spirit being. Jesus has redeemed our spirit already and it is perfect. It is not only free from sin; it cannot sin.
