We can find many incredible examples and promises throughout the bible of the power of God’s Word and ways in which people were used by the Lord to release his word in order to bring breakthrough into impossible situations. In the New Testament Paul wrote to the Ephesians exhorting them to take the sword of the Spirit which is the “Word” of God and to pray. In the Old Testament God told Moses to "speak to the rock" so that its water would be released. As we take hold of the word of God over our lives, we are able to speak to different situations in our lives and in the world around us and release the promise, provision and breakthrough of the Lord into seemingly impossible situations. This is part of our mandate and inheritance as children of God.
