"The detailed attention just given to the Christ-hymn must not obscure the fact that Philippians 2:12-18 are part of a larger parenetic section-1:27-2:18. Exhortation is resumed again through the frequent use of the imperative mood, or through the use of participles with the force of the imperative." [1][source]
"God"s "therefore" ( Philippians 2:9) is matched by the Christian"s therefore ( Philippians 2:12), [2] and that, in a nutshell, is what this passage is about. Just as God assessed and then reacted to the worth of his Son"s life of obedience ( Philippians 2:9-11), so the Christian must ponder the example of Christ and determine upon a worthy response ( Philippians 2:12-18)."
