A prophet, as defined in Exodus, is one who speaks for or on behalf of another, typically a higher-ranking personality. Such a person is sent as a representative, bearing a message from the one who sent him. In diplomatic terms, a prophet can be likened to an ambassador of that person and their nation. As seen in Exodus 7, God placed Moses as God to Pharaoh, with Aaron serving as Moses' prophet. God delivered a message to Moses, who then conveyed it to Aaron, and Aaron spoke it to Pharaoh. In this hierarchy, Moses was God's prophet, while Aaron was Moses' prophet, demonstrating the role of speaking for another in a chain of authority. The function of a prophet is to represent God to the people, often urging repentance and adherence to God's commandments, distinct from the priestly role of approaching God on behalf of the people through ritual. Through examples like Moses, Elijah, John the Baptist, and Amos, it is evident that God's prophets provide clear evidence of being sent by Him, carrying authoritative messages that demand attention and response.

God's oracles are His utterances, His revelation to mankind, communicated through chosen individuals. The Logos Himself, as well as Moses, the prophets, and the apostles, served as oracles of God. Jesus Christ spoke the words of the Father, as God has spoken to us by His Son. Moses gave the people the utterances of God repeatedly, teaching statutes and judgments as the Lord commanded. The prophets, including David, Ezekiel, Jeremiah, Zechariah, and even Balaam, spoke God's words, often receiving direct revelation to convey to the people. The apostles, such as Peter and John, also declared what they saw and heard from God, affirming that their message came from Him and not from myths. God uses people to communicate His message, ensuring that those who speak or write do so according to His oracles, His revelation to man, as good stewards of His grace.

A prophet is best defined as one who speaks for another. A true prophet speaks for God, delivering a message ordained by Him. In contrast, a false prophet speaks for another falsely, either representing the wrong god or claiming to speak for the true God while misrepresenting Him or His words. Often, they speak from their own hearts or for a demonic influence. The core issue is whether someone claiming to represent God does so accurately or falsely. Even if a prophet predicts events correctly or demonstrates supernatural power, if their central message leads people away from the true worship of God, they are false. The False Prophet in Revelation, inspired by the Dragon, will deceive the world with miraculous signs and demonic words, leading people to worship the Beast and commit idolatry. True prophets express God's will in words, often pointing out sin and aligning with His law, while false prophets avoid convicting people of sin and speak soft, easy things for popularity or personal gain. The fruits of a prophet's life and the meaning behind their words reveal their true source, as a true prophet directs attention to God, not themselves, whereas false prophets often focus on personal power, influence, or benefit.
