Scripture personifies God's Word as a living agent that goes forth to accomplish divine purposes. Isaiah declares that God's word shall not return void but shall accomplish that which He pleases and prosper in the thing whereto He sent it. The Word is portrayed as rain and snow that water the earth, bringing forth fruit. The psalmist declares 'He sent his word, and healed them.' In the New Testament, Hebrews describes the Word of God as 'quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit.' This personification reaches its apex in John's Prologue: 'In the beginning was the Word, and the Word was with God, and the Word was God... And the Word was made flesh, and dwelt among us.' The personified Word becomes the incarnate Christ.
For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater: So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
For the word of God is quick, and powerful, and sharper than any twoedged 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.
