Romans 12:21 Do not be overcome by evil, but overcome evil with good.
There are far too many evil things happening in this world for us to ignore the fact there is evil present; but that does not mean we have to give in to it and follow its ways!
Christ first commanded us to not get caught up in evil but to try and spread good instead; the apostle echoes those words reminding us not to be overcome by it but to put it in its place with good acts.
If we try to ward back evil with good; God will continue to back us up in our endeavours to do so. He wants good to shine through so people can have hope and see there is a better way than evil!
