God called everything into being through His Words. When God created the earth, He said, "Let there be." By what we speak, we let things be and become in our lives. If we speak and believe negatively, we are letting the enemy be in our lives. But when we are speaking and coming into agreement with God's Word, we are letting His Word be in our lives. The blessings of God will overtake you if you obey if you let God's Word be in your life.
