What does the Bible say about God's sovereignty over His word?

The Scriptures affirm that God's sovereignty extends over His word, which is described as powerful and effective. Isaiah 55:10-11 states, 'For as the rain comes down and the snow from heaven, and do not return there, but water the earth and make it bring forth and bud, that it may give seed to the sower and bread to the eater, so shall My word be that goes forth from My mouth; it shall not return to Me void, but it shall accomplish what I please, and it shall prosper in the thing for which I sent it.' This indicates that God's word is fluid, actively moving and building toward His divine purposes.
