A decree is an official order or decision. To state or assert boldly, formally, or firmly. "Thou shalt also decree a thing, and it shall be established unto thee..." Job 22:28. In simple terms, to declare something is to say it out loud or to write it down. Make a proclamation. Pray is to ask, seek or petition God. Words spoken have the power to create something out of nothing. Words have power, and when you speak them, you give them life.
