In Genesis chapter 1 when God created the heavens and the earth he spoke into existence what he wanted to see come to pass. When God created man he created man in his image and likeness. So that means we have been given that same power to speak into existence the things we want to see come to pass.
Isaiah 55:11 tells us that God's word will not return unto him void but will accomplish and achieve the purpose for which it was sent. We were created to be speaking beings. It's time to use and walk in the God given authority that has been given to us. Its' time to declare somethings. It's time to give God's word a voice. It's time to say what God says because God's word is powerful, dependable and cannot fail.
