6 the sun will not harm you by day, nor the moon by night.
This verse infers around the clock protection. Not necessarily physically. Satan is our enemy and he hates us and he will attack us. But God is watching, 24/7, around the clock, day and night. He is sovereign and nothing will happen to us without His knowledge, without His presence to get us through it. This verse could also mean that God protects us from natural threats (such as the heat of the sun, the coldness of night). It could even mean from actual threats (sunburn) and perceived threats (moonburn? no such thing, but God will protect us, even from our fears)
Once again, begin your day by reviewing the first verses of the passage. Then add on today's verse. All the verses so far have been fairly short - we're easing you in to things here!
Every day you do this, you're making it a habit. This is not difficult, but it still requires a choice to do it. This is one of the easiest ways I've found to make the Word a daily part of life. But it still requires a deliberate decision to redeem the time. It is worth it!
LeRoy Eims on the importance of Scripture memory: "I think two of the master strokes of the devil have been to convince people he doesn't exist, and that Scripture memory is only for children. He remembers the humility of defeat when Jesus Christ, who was tempted in all points like as we are, met him with the Word of God." (What Every Christian Should Know About Growing; p. 26-27)
