Unlike a daily horoscope, a prophetic word is an encouraging or confirming word inspired by the Holy Spirit.
There are many references in the Bible showing various ways God can speak to us:
“But the one who prophesies speaks to people for their strengthening, encouraging and comfort.” 1 Corinthians 14:3 NIV
“I keep asking that the God of our Lord Jesus Christ, the glorious Father, may give you the Spirit of wisdom and revelation, so that you may know him better.” Ephesians 1:17 NIV
“Blessed are those who listen to me, watching daily at my doors, waiting at my doorway.” Proverbs 8:34 NIV
