"Simple Concerning Evil"
I have heard this argument: How can we comfort and encourage those who fall into a certain sin unless we have gone into those "depths" as well? But this argument is so foolish; it puts the importance on man rather than God. In vs. 19 it says to be wise in what is good, and simple concerning evil. In other words, don't know much about evil.
In the days of the church of Thyatira there were false prophets that arose who would teach this ridiculous argument. They would say "we must know the depths of Satan so that we may combat it". This would encourage others to "experience" sin and claim it was in the name of God. How disgusting was that?
We don't have to experience sin to see the horrible effects it has on people. In fact, keeping away from evil is probably one of the greatest testimonies of God's love and power. It shows that we are so caught up in Gods love and moved by His Spirit living inside of us that we have no desire to even dabble in the smallest of sins. We are to be simple minded to that which is evil, but let us know and experience and dwell upon all that is good and of God. I believe to be wise in what is good leads us to ministry and service for the Lord. Do you know of any ways that we could serve our body and grow in wisdom to that which is good? I would love to know about it!
