โThe Sword of the Spiritโฆ is the Word of Godโ (Eph. 6: 17).
Of all the spiritual armor which believers are told to โput onโ in Eph. 6:11-18, there is only one offensive weapon. This is โthe Sword of the Spiritโฆ the Word of God.โ The Bible is called โthe Sword of the Spirit,โ because the Spirit of God is its Author. It is called โthe Sword of the Spiritโ because, thus written by God who knows all, it can cut deeply. This makes it, for the believer, a formidable weapon against Satan and the forces of evil. We are told in Heb. 4:12:
โThe Word of God is living and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.โ
As David said long ago:
โO Lord, Thou hast searched me, and known me. Thou knowest my downsitting and mine uprising; Thou understandest my thought afar offโ (Psa. 139:1,2).
It is because God knows and understands us so thoroughly that His Word can sometimes cut us so deeply. How wise, then, to bow before that Blessed Book, acknowledge its condemnation of sin and trust the Savior it presents! And, having done this, how wise to โput on the whole armor of Godโ in our stand against Satan and sin, not forgetting to โtakeโฆ the Sword of the Spirit, which is the Word of Godโ! source
