All of us believe in something called Faith. What is faith? Faith is the inner manifestation of your belief and trust in a relation. It is the best way you could express your confidence on a person and it is the binding chord in any relation.
When parents bring up children, they should have faith on them. The least they could do, is to predict something as right or wrong. Faith is the immediate trust that you have on people over a period of time. When you make new friends, there is an untold understanding between both of you , which develops into a bond called faith.
Faith exists everywhere. It is there between friends, it is there between family, it is there between parents and children. Nothing damages a relation more than a breach of faith, so it is a thin chord that ties relations.
It is only faith that keeps the world going in spite of bomb blasts, and accidents. It is faith that helps a person walking on a tight rope millions of feet above the ground. It is again faith that keeps a trapeze artist swinging on top on the ropes. It is faith that brings a child into the world.
Faith is a subjective term, so long as you have it. The moment you lose faith, you begin to view it objectively. Take care of faith, it is fragile.
