Why do a reading plan? Nonfiction is a different breed of books. You aren't simply reading. You are learning. With The Subject of Salvation, you are studying. It's helpful to take in smaller bites of knowledge (or scripture) to better absorb the information. Doing a reading plan allows time to read and reflect on each day's topic. Especially with bible study, it's the most impactful when you go at a comfortable pace. 30 days of reading can totally transform your understanding of who God is, salvation, and your Christian walk.
