The Philippian brethren were laying up treasure in heaven by their love and concern for Paul. They were storing up “credit” with God for the day of the Lord’s appearance. Their consistency of giving was not equaled by any other church. The others gave only sporadically if at all. Paul labored over the Philippian brethren like a mother, and seeing their development gave him great satisfaction. He especially appreciated them because they seemed to respond more than any other ecclesia. They were his “joy and crown” (Phil. 4:1).
