1 John 4:1 NKJV Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world.
1 Thessalonians 5:20-21 NKJV
Do not despise prophecies. Test all things; hold fast what is good.
Inasmuch as it’s up to you, don’t allow just anybody to “speak” into your life. Some people can be classified as false prophets but may not know it themselves. Before you *receive* a prophetic word from someone as the absolute truth, you should test it with the Word and seek the will of God concerning it.
