Another important means is the mobility gained through Christian books and literature sent via mail or passed from hand to hand. The ministry of moving Christian books, magazines, booklets, and Bibles is hardly being used at all. The Christian may be physically immobilized because of his profession or state of health, yet if he used Christian literature, he would not find the Word of God limited just because he himself was immobilized. The objective would be taken in near or distant places, though the Christian was absent.

The giving and sending of books is just the beginning of fast mobile communication of the gospel. The internet can bring to anyone’s living room the most powerful preaching and teaching that is available today. Christian leaders are broadcasting the gospel of Jesus Christ on hundreds of radio stations and podcasts weekly. But this does not guarantee that people will be listening. A phone call, an emailed link, or a blog post to our friends would greatly increase the listening audience.

Then too, we should consider mobility with the use of the weapon itself. If a weapon has a 360-degree field and the soldier keeps it trained in one direction only, then he is not using the weapon’s inherent mobility.

Our weapon, the Word of God, “is living and active, sharper than any two-edged sword, piercing to the division of soul and spirit, of joints and marrow, and discerning the thoughts and intentions of the heart” (Heb. 4:12). We must use it to the maximum of our capability. It has no limitations. The limitations are in us. Let us learn to use the Word as a defensive-offensive weapon. It is a tragedy to see Christians immobilized in a specific witnessing situation because they do not know how to use a very powerful and effective weapon. If we are versatile in the Scriptures, we can strike an effective blow at the place of our choosing. Continual personal study of the Bible is the only adequate preparation for use of the Word.
