Today we know everyone who claims to be a prophet is either lying or crazy. So it would follow that basing your life on their teachings is a bad idea. Wouldn't it make more sense to base your life on the teachings of someone who is smart?
Hebrews 1:1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, 2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
God only used prophets until Jesus Christ came to The World. Now Jesus speaks for Christianity. This is why it's important to know the Bible. So anyone who is claiming to be a "prophet" or "prophetess" today is obviously in complete spiritual error. Knowing God's Word will help you know the real from the fake in this world. And most importantly it will help you know for certain whether you are going to Heaven or not. I hope you are!

Who's to say Jesus wasn't smart? In the bible people weren't basing their life off of the prophets they're basing it off of God's message to the prophets...
