I strongly believe in faith, however we are not some sort of puppets at the hand of faith. It depends on us to make our way in life easier and hapier. Faith has its own role but doesnt work alone, there is a sort of system which depends on all its components in order to work well . Your body is a system, it needs a heart, some lungs, a bit of blood, sometimes a dust of brain in order to function...
"Faith" can only exist in the absence of knowledge or evidence, reason can only work if there IS knowledge and/or evidence.
I believe the faith can give us unthinkable power, if I found my final faith, I think I will keep going with it with any obstruction.
Faith is bot wisdom and comon sense, as it makes an excellent boost for the will: "keep on going, keep on going, it will work, everything will be ok." (never give up)
I believe there is faith for everyone,but I also believe that we can change our faith as long we try to change it.
Whether you believe or not, faith will establish its impression on your life. So better to accept it in righteous perspective.
