Jesus performed many miracles while he was on earth. He doesn't do miracles anymore.
There's no scriptural evidence to suggest that you must have faith you'll succeed or you will fail.
Really? You see my healing coming forth today? That would be nice. I'm a diabetic with bad knees.
Jesus is not on earth to do Miracles physically but He left prophets, men of God who He is using to perform several Miracles in our modern day dispensation.
Do you really think you cant be heal by God from your Diabetics?
