Question: What is a better way of saying "in order to demonstrate this, I will..."? I already use "to that effect" in the same paragraph. I'm looking for something as compact and concise as "to that effect" that will also be a good transition for the beginning of a new paragraph.

Answer: 
Perhaps "To illustrate this, I will...", "Demonstrating this, I will..." or "As an example,.."
Is it appropriate to use "Therefore"?
