The objective of the Body in this life is to live the Grace life. The Holy Spirit does many things for the believer at the time of salvation, and forever afterwards during this life and on throughout eternity. It is very important at this point that you review the wide range of scriptures that describe the Person and work of the Holy Spirit. Please refer to the topical study which was included with Lesson 5. Greek scholars regard the usage in this verse as the nomic aorist, indicating that this is a doctrine that is to be regarded as axiomatic.
Every believer is in one body, elected.
He is the Lord of all believers. A person who says this simply does not understand anything about the relationship between Christ and His Body. And it is horribly misleading to say this because it directs the focus of a person's thinking on himself instead of on the Lord. Christ is always Lord. Everyone is saved the same way.
