"And they were astonished at his doctrine: for his word was with power" (Luke 4:32).

God’s words, whether spoken by Jesus or written in Scripture, are indeed full of power, and it is noteworthy how many and varied are the physical analogies used to characterize and emphasize its power. God’s Word is also called a sharp sword wielded by the Holy Spirit. As part of the Christian’s spiritual armor, we are exhorted to take "the sword of the Spirit, which is the word of God".
 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.  But no earthly form of power can compare to the power in the words of the One who is Himself the living Word of God, the Lord Jesus Christ, for He is actually "upholding all things by the word of his power"
The Father's word is given to us to grant us power and hope and direction to get through this life. (BIBLE Basic Instructions Before Leaving Earth).  IF there is a question the word of God has an answer but often times we do not like the answers that the word of God provides us.
