Adam Clarke on Philippians 1:11

Being filled with the fruits of righteousness - By righteousness we may understand, here, the whole work of the Spirit of God, in the soul of a believer; and by the fruits of righteousness, all holy tempers, holy words, and right actions. And with these they are to be filled, πεπληρωμενοι, filled up, filled full; the whole soul and life occupied with them, ever doing something by which glory is brought to God, or good done to man.

By Jesus Christ - That is, according to his doctrine, through the power of his grace, and by the agency of his Spirit.

Unto the glory and praise of God - God being honored when the work of his grace thus appears to men in the fruits of righteousness; and God is praised by all the faithful when his work thus appears. Every genuine follower of God has his glory in view by all that he does, says, or intends. He loves to glorify God, and he glorifies him by showing forth in his conversion the glorious working of the glorious power of the Lord.
