Rhema (from Greek: "utterance" and by implication "matter" or "topic (of a narration, command or dispute)" is a term used in Christian Theology. God's Rhema, the direct words of God to the individual, can also be imparted through the words of others, such as a preacher in a worship service, or a friend who counsels them. Orthodoxy says that God will not speak a word that contradicts His written word, the Scriptures, so there is a built-in safeguard to prevent misinterpretation. It is easy to see how this can be interpreted both as the bible (God's Word Written) and in the Person of Jesus Christ (God's Word in the Flesh) as seen in John's Gospel, Chapter 1. This occurs because each person is in a different place spiritually in their individual lives so God's word to each of them in that moment of their lives is different - specific to their needs. In other words, the specific guidance we receive from the Holy Spirit at any given time can only be discerned by the general principles laid down in the written word - the Bible. (NIV - "as you have said.")
Luke 3:2 "...the word of God came to John son of Zechariah..." ( NIV - "because you say so" )
John 3.34 "For the one whom God has sent speaks the words of God, for God gives the Spirit without limit."
