My computer screen flashes a little warning sign on those occasions when I try to load too much information onto my hard drive. It tells me my memory is full-it has no more room for any more information.
In a similar way, if we would fill our hearts and minds with God's Word, then when the devil comes with his perverse thoughts and ungodly schemes, he will see a sign that notifies him that our memory is full. It is so important for us to fill our minds and hearts with the Word of God!
Certainly it is good to carry a Bible in your briefcase, pocket, or purse; but the best place to carry the Bible is in your heart. It is good to go through the Word of God, but it is better for the Word of God to go through you. It is great to mark your Bible, but it is best if your Bible marks you. It must affect the way you live.
The Bible tells us to store up its words in our hearts, teach them to our children, and write them down (Deuteronomy 11:18-20). Memorizing a verse may not feel like a supernatural experience, but it is an important discipline. That is why the Lord told Joshua to meditate on His Word "day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success" (Joshua 1:8).
When you store the Word of God in your memory, the next time you face a difficult situation, suddenly that verse will come to you with freshness from the very throne of God. It will speak to your situation and strengthen your heart.
So get God's Word into your heart and mind! And put it into practice.
