Philippians 4:1 - Arthur Peake's Commentary on the Bible

Php_4:1. Steadfastness. Paul introduces his exhortation to steadfastness with the word wherefore, so as to base it on what he has just said about the coming of Christ and its expected effects, and he enriches it with an affectionate reference to the relation of the Philippians to himself. In a peculiar way it is they, of all his converts, who give him joy, and whom he regards as like a festive garland or a victor's wreath, since they especially illustrate in their lives and characters the success of his ministry.
