"What then is the gift of prophecy? Well I would define it as a direct inspiration of the Holy Spirit. What for? It's purpose is to give a word from God or the Word of God to the Church. Prophecy is the inspired delivery of warning, exhortation, instruction, judging and making manifest the secrets of the heart. Someone who makes a prophecy has been given this gift of passing on, as it were, a word from God to the church and to individuals in the church".
