Fortune-telling is bad for your health. Evenif you try to use God Word as your ouija board. A neurotic anxiety to know what the future holds is incompatible with joyous confidence in the God who holds the future.
I agree to part of what you say. Bible prophecy is not "fortune telling". But you are right that we need to be joyous in our Christian walk. We should read the Bible like one would read a road map...The Holy Spirit guides us in all truth...We must know the signs and what they mean. That's not fortune telling. That's doing what Jesus tells us to do. So we won't be deceived.
