Many people seek, as if essential, a spiritual father who leads an exalted life, and they become despondent when they do not find such a one, and therefore they rarely, almost reluctantly, come to confession. This is a great mistake. You need to believe in the very Mystery of Confession, in its power, not in the person who performs the Mystery. It is essential only that the spiritual father be Orthodox and authorized by the Church. You need not argue that the personal qualities of the spiritual father are important, but you should believe and know that the Lord, active in every Mystery through His Grace, acts according to His omnipotence, regardless of these qualities.
