I believe that one of the most neglected spiritual discipline is that of Scripture memory. If you think about it, those of us who grew up in church memorized a lot of Bible verses as children. We memorized verses to get candy bars in Junior Church. We memorized verses to win points at Vacation Bible School. At a summer camp that I attended, it was possible to earn points for your team by memorizing what was known as a "Sword", a group of six verses in a row. Almost every kid in my cabin would attempt to memorize Psalm 136 (look it up and you'll understand why). One time I earned a scholarship to camp for memorizing the most Bible verses one week. Awana, Word of Life, Sunday School...the list goes on of places that we memorized Scripture as children.
However, once we left middle or high school, the importance of Scripture memory is no longer stressed. Ask anyone and they will tell you they either can't memorize or don't have the time.
In response to this, I am suggesting that we work together to memorize a Bible passage per week. By spending a little bit of time each day memorizing and reviewing the passage, you will have an incredible tool at your fingertips to help you fight sin that you may be faced with (Psalm 119:11). Continue this for a year and you will have at least 52 verses or more memorized.
The verse to learn this week is Ephesians 6:16-18. I have listed the passage below as it is found in the English Standard Version (ESV).
 In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one;
 and take the helmet of salvation, and the sword of the Spirit, which is the word of God,
 praying at all times in the Spirit, with all prayer and supplication. To that end keep alert with all perseverance, making supplication for all the saints,
(Ephesians 6:16-18 ESV)
