Here are 3 ways to combat the godless culture. They are not necessarily easy, as they require discipline, but if you are a Christian and want to keep the godless influences out of your life they are necessary.
1. STAY in God's Word daily.
2. SHUT off the television, or be VERY selective in what you watch. The same applies to other media.
3. SHOUT to satan to leave you alone. As Christians, we have authority over satan, in the name of Jesus. Know where you are weak and most vulnerable to the attacks of satan. Exercise this authority during these times and during times of adversity.
These things will work if you exercise discipline to do them.
