Phil 1:6-7 6 And I am convinced and sure of this very thing, that He Who began a good work in you will continue until the day of Jesus Christ [right up to the time of His return], developing [that good work] and perfecting and bringing it to full completion in you. 7 It is right and appropriate for me to have this confidence and feel this way about you all, because you have me in your heart and I hold you in my heart as partakers and sharers, one and all with me, of grace (God's unmerited favor and spiritual blessing). [This is true] both when I am shut up in prison and when I am out in the defense and confirmation of the good news (the Gospel). AMP
