Faith, in it's biblical definition, it is the substance of things hoped for; the evidence of things not seen.
Amy, if I may? Look at that again ... faith is substance and faith is evidence. Faith comes from God; we can ask for it and I believe when we do He provides the substance and the evidence by which we grow in trust and by which we believe.
What is the evidence He has given you?
