Hebrew 4:12 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.

Two very important things the word of God will do to you after which it must have cleansed you is to make you alive and make you powerful.

“For the word of God is Quick(alive)…”
Anyone who comes in contact with the word of God comes back to life. Such person is re-invigorated and (s)he is restored to life. Remember the scripture saying “And you hath he quickened, who were dead in trespasses and sins;” Ephesians 2:1. Man was dead(separated from life) in sin and so the word of God cleans and restores life back in us. Also remember Jesus saying, “…the words that I speak unto you, they are spirit, and they are life.” John 6:63.
So, let the word of God stir up life in you. To be alive is to be activated in life. Eternal life is not just long unending life, it is a higher quality of life that lives above sin and death. The word of God will restore life in you in Jesus name.

“…and powerful”
The word of God has capacity of making you powerful. What created the world we live in is the word of God and remember that word is also God, for it was by the Word that all things were made and there was nothing made outside the word. Hence, all the things in this world are subject to the word because what also sustains the world is the word of God. We see the scripture saying, “through faith we understand that the worlds were framed by the word of God,….” Hebrews 11:3. In Jesus’ response to the tempter, he said, “But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.” John 4:4.
The sustenance of life are not in the things that this world provides, but in the word that proceeds out of the mouth of God. Therefore, to be strengthen with might, you need to be a consumer of the word of God on a daily basis. To be powerful also means to be strong. We have many people who are weak and beggarly. That’s what the world provides them with and that’s what they seek after all their lives. Gal.4:9 “But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage”

So, we can not afford to live our lives outside the word of God, hence we’ll become dead and powerless. Any man that lives outside or without the word of God will be dead, running after dead things, and will be powerless, seeking after things that amount to nothing(powerless things). God bless you with His word and prosper you by His word. Amen.
