Php Philippians, chapter Epistle to the Philippians, chapter 1
I thank God and rejoice because you have been working together with me to make known the good message from when you first believed until now.
Philippians 1:3-8
During this time that I have been a prisoner [MTY] and during the times I was previously able to defend the good message about Christ and proved/confirmed to others that it is true, all of you have been sharing with me (OR, have helped me) in this work that God kindly gave to me to do. So indeed it is right that I feel joyful about you all, because you are very dear [IDM] to me.
