Faith is regarded as the substance of. as such is not blind faith at all because it has substance. it adds up in ones Soul and the lights go on that such is in fact true and that is how we arrive at reality of our Faith in such.
Bible says, "Oh you of little faith" ? so one has some faith in what we were informed about as in regards to the Bible or Priest or whoever talking about such things. so faith Biblically their is more to faith than one in that regards, what is hoped for is "The faith that can move mountains". one has to truly be born again to have that faith, it's because it's solid. so as one starts off with only being able to deal with consuming milk and can not deal with solid food.
A little faith is fine, better than noting, but such can grow. take the Bible for example, we see this in the parable of the sower, where the seed falls and some spring up directly but fail for they have not roots and some grow more so but are choked by the weeds and their faith dies. I have seen such of people who once I remember at Bible study had faith and now they have turned to me and said you still do not believe that rubbish do you and I say back, yes I sure do ! absolutely ! not to mention hat my faith has grown so much more so, that I have absolute faith in Jesus Christ, come hell of high water, as I live and breath he is within me and I am within him as one, so to speak. I have no doubts as to Jesus Christ at all what soever. I did not know him but I knew of him and then I came to know him, in fact he came to me in a flash and I instantly knew him just out of the blue, something much like as Saul experienced when he became Paul.
Grace however is due only to God working in us, that we abide such as that. such is not of our merit, it comes by our abiding in the Holy Spirit. or it does not come from us one can say. it's a work of God in us.
