consider these words from Jojo Reinhardt.
"The Sword of the Spirit is the Word of God. It is both offensive and defensive – it pierces and protects. The Word of God is the written word (Bible) and the spoken word (Holy Spirit). It is Jesus as Logos incarnate who was with God in the beginning (1 John 1-2). It can pierce the darkness with the light of Truth (1 John 1:5). The Word of God can pierce any shield (heart) and any helmet (mind) if wielded properly and with care. The entire world is filled with ideas and philosophies and teachings (and even laws) that run contrary to God’s will. As we read and learn and re-read and learn more, the Word of God will become written on our minds and hearts. Our “weapon” will be kept sharp and readily available. The Holy Spirit will bring forth the right Scripture at the right time in every situation we may face. You will be able to draw your sword and apply Truth."
