Wikipedia's explanation of faith begins with this statement: "faith is belief in an idea that is unsupported or contraindicated by evidence...largely reserved for concepts of religion."
That is not faith. That is stupidity.
Faith is not something for weak minds or emotional morons. True faith engages the mind, emotions, and will for a confident expectation of advantage. First of all, for there to be real faith, the mind must be engaged. Real faith is founded on facts first, while blind faith, which is what Wikipedia writers are describing, is not concerned with reality, fact, or truth. Blind faith says "My mind is made up, don't confuse me with facts", while real faith wants the facts, seeks the Truth, and moves forward from there. Faith, without some foundation in fact, is only fantasy.
Next, for there to be real faith, the emotions must be involved. There is no faith without feeling, and the emotional expression of faith is an important part of the experience. For instance, when two people are joined together in marriage, this is an act which requires significant emotional devotion in order to persevere through good times and bad, sickness and health, etc. For an entrepreneur to take their life savings and risk it all on a business venture requires a belief in the viability of the business plan and their own personal skills and willpower, despite the lack of any solid guarantee of profit. But to rely strictly on emotions in matters of business, religion, relationships, or just life in general is to surrender logic or truth to the whims of sensation. On the other hand, to deny emotions any contribution to daily living is to live without passion and die without love.
And finally, for there to be real faith, the Will must be involved. You can know something (mind) and you can feel something (emotion), but until and unless you do something (action), what you know and what you feel will rot away in a neglected corner of your mind and heart. Many people, afraid to act upon what they know and what they feel, live their life full of bitterness and regret. They spend their days wondering what would have happened if they had only..... Well, you fill in the blank spot. Faith happens when what you know and what you feel are balanced with a brave and fearless move forward.
For most of us, there are two roads by which we may move forward into tomorrow. One is the road of doubt and despair, and the other is the road of faith and hope. In all likelihood, you will find great fulfillment and personal success when your head, heart, and will-in grand agreement-decide to take that step into tomorrow!
