Brother Duane uncovers the spiritual significance of foot washing, as Jesus demonstrated by washing the disciples' feet with water and a towel. Through this act, we see the mirror image of the spiritual cleansing of our minds and bodies, the concept of being born again, and the Holy Spirit's constant renewal of our inner selves. The cleansing power of God's Word purifies and sanctifies us, serving as the ultimate truth against the deceiving philosophies of this world.
