Philippians 1:7

1:7 For it is right for me to think this about all of you, because I have you in my heart, since both in my imprisonment and in the defense and confirmation of the gospel all of you became partners in God’s grace together with me.

Philippians 3:9

3:9 and be found in him, not because I have my own righteousness derived from the law, but because I have the righteousness that comes by way of Christ’s faithfulness – a righteousness from God that is in fact based on Christ’s faithfulness.
