The best definition I can find of faith is the dependence upon the veracity of another. The Bible definition in the 11th chapter of Hebrews is, 'Faith is the substance of things hoped for, the evidence of things not seen.' In other words, faith says amen to everything that God says. Faith takes God without any ifs, If God says it, Faith says I believe it; Faith says amen to it.
