As we are inundated by the "hollow and vain philosophies" of the world, we must be careful not fall into the temptation to accept as "normal" what is contrary to God's Word, because studies show that the vast majority of believers don't even have a Biblical worldview.  While Christianity is growing in hostile countries in Africa and Asia, western countries are falling for 4 lies designed to hijack Truth.   So we have to guard our minds by "taking our thoughts captive", and focusing on Christ.  Video of this service is also available:  https://www.youtube.com/watch?v=58c0MQalIIY&t=11s
