“I want you to be wise about what is good, and innocent about what is evil.” Romans 16:19b
It’s not a good thing for a Christain to be savvy about sin. Sin is supposed to become an abhorrent and a foreign thing in the life of a Christian. We are not to deliberately indulge in sin, nor are we to think about it (Rom. 13:14). Rather, we are to think about how our lives can glorify God, and do those things. In doing so, we will stand out from the people of this world. Some might ridicule us, but others will be drawn to the light of Christ that shows in our lives.
Wisdom is more than just knowledge, it is the right application of that knowledge to our lives. We are to know the things that please God, and do them appropriately. We are to be innocent about evil. We don’t need to investigate lewd websites, movies, or TV programmes to know how bad they are, or so we can talk about them with our non-Christian friends and ‘be relevant’ to them. No – fill your life with good things, things that glorify God, and purge the evil.
