For thousands of years humans haved looked into the night sky and studied the moon. We've wondered how it stays up there, where its light comes from, what it is made of, and a number of other questions. Some speculated that the moon was made of green cheese, others thought it was mud, and others said solid rock. In a similar respect, theology can be considered speculation about God. We try to map the divine through observation, human reasoning, revelation, and historical understanding.
Theology likewise is an attempt to know the unknowable.
Your theological approach determines how you seek your personal understanding about God. It might not be that hard with a 25 or 50 piece puzzle, but it is near to impossible with 1000 and 2000 piece puzzles. And there are many different strategies for putting a puzzle together. Others build the boarder first. Still others just dive-in and attempt to randomly match pieces.
