1 John 4:5

They (who teach twisted doctrine) are of the world and belong to it; therefore they speak from the (viewpoint of the) world (with its immoral freedom and baseless theories-demanding compliance with their opinions and ridiculing the values of the upright) and the (gullible one of the) world listens closely and pays attention to them. 

As Christians, we need to read our guidebook (the Bible) and renew our minds to what is true from God. The world constantly sends out distorted messages and partial truths to pull believers away from the faith. We need to keep our guard up to protect our families, our communities, and our nation. Jesus said we are to occupy until He returns.
