"The word of God is living and powerful, and sharper than any two-edged sword, sharp even to the divisions of our soul and spirit, and of joint and marrows, and is a discerner of the thoughts and intents of the heart."(Hebrews-4:12)
Even at this very moment the word of God is at work in the world. It is an active force that rules the spiritual activities in the whole Universe. It changes things, especially when it is spoken and believed, both in the hearts of men and in their circumstances. God is observing over his words to perform it(Jer.-1:12).Every seed brings on life after its own kind. The seed of the word of God, if planted well in soft and open heart, will develop the life, character and faith of the followers of God.
For hard heart, the word of God correctly applied will be like hammer to break the hard heart open(Jer.-23:19).
The word of God is compared to a fire. “‘Is not my word like a fire?', according to the LORD, 'And like hammer that break the rock in pieces?' “(Jer.-23:29). It can behave as a fire(Jer.-5:14; 20:9). Fire scatters, illuminates, warmth, energy and comfort-but it can also demolished. The word of God ruins the power of evils when it is believed and applied. It can break Lucifer's determination to conquer our hearts and lives.
Water is also compared to the word of God (Eph.-5:26; Ps.-1:1-3). Water cleanses, refreshes, life and encouragement and satisfies the thirsty. The word of God can also do this for us.
Mirror is also compared to the word of God which shows us our true spiritual state(James-1:23; 2Cor.-3:18). It only shows us how we need to be cleansed from our sins.
