“And this I pray, that your love may abound yet more and more in knowledge and in all judgment; That ye may approve things that are excellent; that ye may be sincere and without offence till the day of Christ. Being filled with the fruits of righteousness, which are by Jesus Christ, unto the glory and praise of God” (Philippians 1:9-11).
“Fruits” are “the results of work or activity.” Who exactly is working?
Works-religion parading as “Christianity” has led us to believe that Christian living involves us making ourselves holy by working to keep rules and regulations. However, the Bible says Christian living is “being filled with the fruits of righteousness, which are by Jesus Christ.” This is not self-righteousness, what religion produces. It is not artificial or superficial righteousness, what religion generates.
Nay, it is true righteousness, a new (righteous) nature in Christ and its resultant actions. First Corinthians 1:30: “But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:….” If we have trusted Jesus Christ as our personal Saviour, we share His identity—He is our wisdom, He is our righteousness, He is our sanctification (holiness), and He is our redemption (freedom from sin). From Him springs forth our righteousness. From Him working in us through the indwelling Holy Spirit, righteousness abounds in our hearts and lives.
First Thessalonians 2:13: “For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.” Ephesians 3:16 says: “That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;….” Finally, Galatians chapter 5: “ But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,  Meekness, temperance: against such there is no law.” There is the life of Christ, friend, in its fullness, available by daily faith in Him… something religion can never produce! source
