Having a biblical worldview is critical for a Christian striving to live a godly life in this world. The culture we live in is very blatantly anti-Christian and undermines the Bible in deed and thought. If we are not careful to cultivate critical thinking and a biblical worldview, it is easy to fall prey to the lies of popular culture and society.
In order to do this, we need to be reading our Bible and be using it as our standard in making decisions. The Bible is very clear on some issues, and whether or not it is the popular view, as Christians we are to follow what the Bible teaches, not society around us.
Some excellent books on developing a biblical worldview are:
Total Truth by Nancy Pearcey
Think Christianly by Jonathan Morrow
How Now Shall We Live by Charles Colson & Nancy Pearcey
I have several other books on this subject but not having read them yet, don’t want to recommend without reading first.
