- Scripture memory makes it possible to meditate on the Scriptures at times when a Bible is not available. Meditation is the pathway to deeper understanding.
- Memorization strengthens your faith because "faith comes by hearing, and hearing comes by the Word of God." If the word is in your head already you can replay it, "hearing" it again and again.
- Memorization shapes the way I view the world by conforming my mind to God's.
- Memorizing Scripture makes God's Word more readily accessible in overcoming temptation to sin, because God's warnings and promises are the way we conquer the lies of the devil.
- Memorizing Scripture guards my mind, making it easier for me to detect error. The world is filled with error because the god of this world is a liar.
- Memorizing Scripture enables me to hit the devil in the face with a force he cannot resist, to protect myself and my family from his assaults.
- Memorizing Scripture provides the strongest and sweetest words for ministering to other people who are in need.
- Memorizing Scripture provides the matrix for fellowship with Jesus unlike anything else. He talks to you here in prayer so sweetly and powerfully, and authentically.
