Here are a few Bible passages that may be helpful in answering your question:
"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. By this you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess that Jesus Christ has come in the flesh is not of God..." - 1.John 4:1-3
"To the law [books of Moses] and to the testimony [the writings of the prophets]! If they do not speak according to this word, it is because there is no light [truth] in them." - Isaiah 8:20
“Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves. You will recognize them by their fruits [deeds]..." - Matthew 7:15,16
"Do not be conformed to this world, but be transformed by the renewal of your mind [toward God], that by testing you may discern what is the will of God, what is good and acceptable and perfect." - Romans 12:2
"Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things. " - Philippians 4:8
The last verse may not directly answer your question, but can provide some boundaries to help in determining what might be true or false.
