Thirdly, knowledge itself is often built upon faith. One cannot come to knowledge through absolute skepticism. Also, in relation to almost all written words, particularly those which relate to history, the reader is called to an act of faith. It is true to say that certain things always remain obscure and meaningless unless they are viewed in the light of faith which then provides a way of explaining and understanding their existence and meaning. Thus, for example, the phenomena of suffering and death would be understood differently by one who believes in Christ than by one who believes in some other religion or philosophy or in none at all.
Faith is always personal.
Each person must believe for himself. No one can believe for another. Many people may believe and trust the same things because of a unity of their knowledge, reason, experience and convictions. There can be a community of faith and a unity of faith. But this community and unity necessarily begins and rests upon the confession of personal faith.
