Master Evil with Good

How can we master evil in the world? Rom 12:21(1-20) "Do not let yourself be overcome with evil, but overcome or master evil with good." What is good? Looking at the preceeding verses, we can see what is contained in good. Each one of these are deep, rich and worthy of study and meditation! #1-vs1-Make a decisive dedication of your body to be holy and well pleasing to God; #2-vs 2-Do not adapt yourself to the external and superficial customs of this world, BUT transform your mind (attitude and ideas) by renewing it, and prove what is good, acceptable and the perfect will of God; #3-vs3-Don't be proud and arrogant>be humble and realistic; #4-vs9-let your love be sincere; #5-vs 9-hate evil and turn from it, hold on to what is good; #6-vs10-love on another with brotherly affection, show honor and preference; #7-vs11-be zealous and "on fire" for God, serve the Lord; #8-vs12-rejoice in hope; #9-vs12-be steadfast; #10-vs12-be patient in tribulation; #11-vs13-constant in prayer; #13-vs13-contribute to the needs of God's people; #13-vs13-be hospitable; #14-vs14-bless your persecutors; #15-vs15-rejoice with those who rejoice and weep with those who weep; #16-vs16-don't be a snob, do humble tasks and adjust yourself to things and people; #17-vs17-be above reproach and don't repay evil for evil, consider what is honest and noble; #18-vs18-as far as it depends on you, live at peace with everyone;#19-vs19-don't be vengeful; #20-vs20-give your enemy a drink if he's thirsty or food if hungry. How can good overcome evil? My husband has been making a point in his recent series that I believe these verses speak to. He asks, "What's wrong with the world? ME! Say it...ME!" It starts with me! We can't change the world without changing ourselves first. This is how we will master evil!
