Words of Death
Anything you hear that is not encouragement, building you up and pushing you closer to God is not of Jesus, Holy Spirit nor of God. Hate is the action that tears a person down. It is the opposite of Love.
Words of Life
Love is the action that builds someone up, it is the opposite of hate. Any word that you receive that edifies you, exhorts you or consoles you, is of Jesus, Holy Spirit and God.
Do not be deceived, God is not mocked; for whatever a man sows, this he will also reap. For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life. (Galatians 6:7-8)
