Your word I have hidden in my heart, that I might not sin against You.
Psalm 119:11
Consider all the things you know by heart: your birth date, telephone number, social security number, home address, and more. How is it that we have memorized those items without really trying? By repetition and by reciting them when we need to. We are protected from the dangers of confusion by being armed with this data.
Memorization is a powerful tool, a defensive tool. We can think of memorizing Scripture in the same way—as a defense against impurity and sin. The psalmist said that he hid God’s Word in his heart so that he might not sin (Psalm 119:11). Memorizing Scripture is a sure defense against sin.
The easiest way to begin Bible memorization is to start with a verse you are already familiar with. Review it daily until you know it as well as your own phone number! (D. Jeremiah)
