Happy New Year! May 2011 be full of peace and joy for you.
Php 4:14 Notwithstanding ye have well done, that ye did communicate with my affliction.
Php 4:15 Now ye Philippians know also, that in the beginning of the gospel, when I departed from Macedonia, no church communicated with me as concerning giving and receiving, but ye only.
Php 4:16 For even in Thessalonica ye sent once and again unto my necessity.
Php 4:17 Not because I desire a gift: but I desire fruit that may abound to your account.
Php 4:18 But I have all, and abound: I am full, having received of Epaphroditus the things which were sent from you, an odour of a sweet smell, a sacrifice acceptable, wellpleasing to God.
Paul is wrapping up his letter now, thanking them once again for their helpful contribution. They were the only church that was helping him out, and they'd done it more than once. Giving to others, such as Paul, is pleasing to God.
