Take no part in the unfruitful works of darkness, but instead expose them. (ESV)
In yesterday's devotional we looked at the need for Christians to avoid the sinful acts of darkness. The more that we engage in sin we dim the light of Christ within us and non-believers are unable to see any difference in our lives from theirs. We ought to always be about the things that promote the glorious Gospel of Jesus Christ.
Paul says that we are not only to avoid works of darkness, but rather, expose them. I believe that Paul's emphasis here is on exposing the works of darkness that have been embraced by believers in Jesus Christ. Because the enemy of our souls is always trying to deceive us we are prone to fall into sin. We can easily fall into darkness.
A godly person will see a brother or sister who has fallen into darkness and lovingly confront them. Now, I must emphasize that we must be loving. We are just as prone to fall into the same sin, so we have no place to bring condemnation. In fact, sin itself brings condemnation. You do not have the gift of condemning others. Here is how Paul instructs us to confront sin in our brother or sister in Christ:
 Brothers, if anyone is caught in any transgression, you who are spiritual should restore him in a spirit of gentleness. Keep watch on yourself, lest you too be tempted.  Bear one another's burdens, and so fulfill the law of Christ. (ESV)
Do you sense the love and gentleness that is involved in exposing darkness in our brother or sister in Christ? This is also a reflection of how our Savior deals with us; lovingly and gently. If you are thinking of being used to expose darkness make sure that you have a loving and gentle heart. If you don't you are not ready to be used in that way.
One of the best ways to not fall into darkness is to hold yourself accountable to another brother or sister in Christ who you will agree to let them expose your darkness and vice versa. Ask the Lord to help you find such a friend. It is essential.
