"See to it that no one takes you captive through philosophy and empty deception, according to the tradition of men, according to the elementary principles of the world, rather than according to Christ. (Colossians 2:8)
What we believe, the way we view and understand things depends, of course, upon who we trust. Most people live their lives trusting their own experiences through what they can see, hear, taste and feel. Our world view is formed early in life by our experiences, as well as, by our parental training and education.
As the Bible says, most people continue walking by sight alone rather than by faith. They have physical sight (experiences, training and education), but they are spiritually blind. Those who are spiritually blind are ignorant regarding the wisdom of God. They must depend solely upon the wisdom of man and their experiences. As Solomon writes in the book of Ecclesiastes, their world view is limited by those things that are "under the sun". Here is Solomon's conclusion about the world and its limited human wisdom; I have seen all the works which have been done under the sun, and behold, all is vanity and striving after the wind. (Ecclesiastes 1:14)
As Christians we are to walk by faith, not by sight(2 Corinthians 5:7). Again, what we believe, the way we view and understand the world depends on who we trust. Our enemy tries to take us captive through the worldly philosophies and the empty deceptions of human wisdom. But if we have Christ and His Word, we have the true and sufficient wisdom of God; seeing that His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence. (1 Peter 1:3)
