a lot of people want proof that GOD exists that HE still performs miracles but what does hebrews 11:1 say? now faith is the substance of things hoped for the evidence of things not seen in other words faith is believing even if you cant see the end results right away. let me give you a personal example my grandprarents were ministers all of thier children backslid every day my grandmother prayed for us to return to the LORD she believed HE would answer her prayer not because of what she saw but because of who she trusted i myself am having that same faith with my sons healing i cant see his healing now but i know who i trust i know who i believe so therefore i dont need visual proof of GODS healing power. yes sometimes faith waivers but thats why knees bend and heads are able to bow and hearts have the ability to be humbled
