Should we test our entertainment choices by Scripture?

Prove all things; hold fast that which is good. (I Thessalonians 5:21)

In context, Paul is speaking of conduct within the church. At the same time, what can applied to the testing (proving) of things in the church must also be applied to the daily life of the believer. Of course, testing inevitably involves making a judgment about what is right and what is wrong. This itself is a hurdle many people have no desire to confront. If, though, you profess the Scriptures as your authority, you are obligated to test all of your activities according to the Scripture. (Incidentally, those who do not profess the Scriptures as their authority may not be hypocritical in that regard, but make no mistake, your activities will be ultimately judged according to Scripture. Read John 12:48.)  

For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:...proving what is acceptable unto the Lord. And have no fellowship with the unfruitful works of darkness, but rather reprove them. (Ephesians 5:8, 10-11)

Two truths come to light here. The first is that believers are commanded to prove (discern or test the genuineness of) what is acceptable to the Lord. The second is that there is to be a separation from the unfruitful works of darkness. Hollywood, anyone?
