What do you have faith in? If it is in yourself, then pride has blinded you. If it is in your fellow man, you probably haven't lived long enough or don't have close relationships with others. We as humans are guaranteed to be a disappointment at some point. 'We all fall short of the glory of God.'
Hebrews 11:1 ''Now faith is the substance of things hoped for, the evidence of things not seen.'' Faith is confidence and trust in something. In this verse, faith is the evidence of where our trust lies regardless of the situation of what we see.
I think Job is one of the great stories of unshaken faith. There was nothing the devil could do to him that made him lose his faith in Christ. Loss of possessions, loss of loved ones, slanderous remarks, and painful afflictions were not enough to break his relationship with God.
Is your faith in God that strong? Can you believe that everything that happens to you is for your good?
