"For the word of God is quick, 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 (Hebrews 4:12). Whose voice then shook the earth: but now he hath promised, saying, Yet once more I shake not the earth only, but also heaven.Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear: For our God is a consuming fire. (Hebrews 12:26,28-29)
The Word (Jesus) of God is powerful. It (He) is alive, active, and all powerful; able to see through man's soul and spirit. The Word (Jesus) introduces man to the Holy Spirit Who provides man (whosoever will) with power to deny the lust of his flesh. God will consume anything and everything that is not wrought by Faith in Christ Jesus and the Cross.
"God is a Spirit: and they that worship him must worship him in spirit and in truth (John 4:24). Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord (1 Corinthians 15:58).
