Explaining faith to those who doubt the existence of faith can be summed up similar to this, which surprisingly supports the existence of faith that can be found in everyone.
A man (woman) agrees to take a job with a company. The company tells the man that he will be paid every two weeks. The man agrees to the terms and accepts the job. The man reports to work the first day, works eight hours, and afterwards, he goes home. The next day the man repeats what he did the first day. The man does the exact same thing for one week straight. This is a classic example of faith in action. The man has placed his faith in the company, believing that he will be paid when he gets to the end of the pay period, which is supported by him going to work every day and not getting any form of compensation during the period. Payday comes and the company gives the man his first paycheck. Now that the man has his paycheck, he does not need faith anymore because the thing that he had hope for, the thing that he believed he was getting from the company is now a reality.
“Now faith is the substance of things hoped for, the evidence of things not seen (Hebrews 11:1 KJV).”
“Now faith is a well-grounded assurance of that for which we hope, and a conviction of the reality of things which we do not see (Hebrews 11:1 Weymouth New Testament Translation).”
“Now faith means that we are confident of what we hope for, convinced of what we do not see (James Moffitt).”
