Reading this book will give you many facts and some truth. Studying, meditating and praying over the word and facts about the blood will produce truth. Truth is a product of the Holy Spirit. Truth comes with time. It comes with persistence.
Truth is life and like all living things it grows and dies.
The more time you spend with God, the more your faith will grow and a greater understanding of the truth will be available to you. Facts are kept in our head. Truth is kept in our heart. Satan looks at the facts but is moved and defeated by the truth. Simply insert your own values between the double-quotes.
