Thanks for your careful exposition of this passage.

I agree that this passage is addressed to the church and not the individual. Note in my exposition of 2:13 that I make the point that “salvation” there does not refer to individual salvation but to the salvation of the local church from schism (note context of chapter and the entire book–dealing with schism in the church as found in expressed in two persons in chapter four). However, the church is made up of a collection of individuals. What is true of the church as a whole can be true of the individual as well (depending on the context).

Did I say explicitly that this passage deals with eternal security? Eternal security is an application of the principle.

I agree as well with your point that Paul addresses the work of the church. The church was in danger of a split and needed to consider the principles of unity. That is why he said that God would “complete” what He started.

Thanks for your excellent blog.

First, in the context, Paul is not discussing salvation but rather his partnership with the Philippians (specifically their financial support).

Second, you here is plural (among you) so it is not referring to individual people but to the group as a whole.

Third, this is teaching that it will happen until the day of Christ Jesus (the return of Christ). If this is referring to sanctification then that would stop with the death of the person and would not continue until the day of Christ’s return. So, it makes more sense that this refers to God’s overall superintending of the spread of the gospel to the whole world. In other words, Philippians 1:6 is assuring the Philippians that they are sharing in God’s eternal work of spreading the gospel (vs. 7) which will indeed culminate in the return of Christ Jesus.
