Contradiction with Philippians 4:12
This verse shows Paul speaking of knowing how to live both in abundance and in need, which contrasts with the idea of coming "in the fulness of the blessing" as stated in Romans 15:29.
Philippians 4:12: I know both how to be abased, and I know how to abound: every where and in all things I am instructed both to be full and to be hungry, both to abound and to suffer need.
