For such men are false apostles, deceitful workers, disguising themselves as apostles of Christ. No wonder, for even Satan disguises himself as an angel of light. Therefore it is not surprising if his servants also disguise themselves as servants of righteousness, whose end will be according to their deeds. (2 Corinthians 11:13-15)

It takes a willful naïveté to deny that such a thing could happen in our time. As a matter of fact, it is happening on a massive scale. Now is not a good time for Christians to flirt with the spirit of the age. We cannot afford to be apathetic about the truth God has put in our trust. It is our duty to guard, proclaim, and pass that truth on to the next generation (1 Timothy 6:20-21). We who love Christ and believe the truth embodied in His teaching must awaken to the reality of the battle that is raging all around us. We must do our part in the ages-old Truth War. We are under a sacred obligation to join the battle and contend for the faith.
