The reason why people are either incurable optimists (a person who see hope in the future) or incurable pessimists (a person who believes the worst of the future) is because both persons work on the principle of faith and whatever you have faith in tends to happen which in turn crystallizes your belief system.
Job proved this principle in Job 3:25 when he testified that “the thing which I greatly feared is come upon me, and that which I was afraid of is come unto me”.
Job was afraid of the future and his fears came to pass.
The woman with the issue of blood had had her condition for twelve years, yet, she remained an optimist and because of her hopefulness for the future, “she said to herself, “If I only touch his cloak, I will be healed” – Matthew 9:21. And what she hoped for became her reality.
These two situations are proof positive that whether you expect good or bad, you will never be wrong. Furthermore, the woman with the issue of blood proved that the length of your negative situation does not have to turn you from an optimist to a pessimist.
