As we look around us, I believe God is asking, "Who will take a stand for me against evildoers?" (Psalm 94:16). God instructs us to "destroy arguments and every lofty opinion raised against the knowledge of God" (2 Corinthians 10:5).
Christians can't just sit back as we clearly see a spiritual battle around us, we need to "contend for the faith" (Jude 1:3). And here's one of the reasons I'm on Twitter and Facebook: "Take no part in the unfruitful works of darkness, but instead expose them." (Ephesians 5:11)
