Why doctrine matters and where it can lead, from Steven Lawson at the Ligonier Ministries blog:
The Continental Divide of Theology
Category: Reformation Trust
Through the western regions of North America, there runs an imaginary geographic line that determines the flow of streams into oceans. It is known as the Continental Divide. Ultimately, precipitation falling on the east side of this great divide will flow into the Atlantic Ocean. Likewise, water falling on the western slopes of this line will surge in the opposite direction until it finally empties into the Pacific Ocean. Needless to say, a vast continent separates these immense bodies of water. It is seemingly far-fetched to ponder that a raindrop falling atop a mountain in Colorado will flow to the Pacific, while another drop, falling but a short distance away, will flow into the Atlantic. Nevertheless, once the water pours down on a particular side of this great divide, its path is determined and its direction is unchangeable.
Geography is not the only place we find a great divide. There is a high ground that runs through church history as well—a Continental Divide of theology. This great divide of doctrine separates two distinctly different streams of thought that flow in opposite directions. To be specific, this determinative high ground is one’s theology of God, man, and salvation.
