I have a dogmatic certainty: God is in every person’s life. God is in everyone’s life. Even if the life of a person has been a disaster, even if it is destroyed by vices, drugs or anything else—God is in that person’s life. You can and must try to seek God in every human life. Although the life of a person is a land full of thorns and weeds, there is always a space in which the good seed can grow. You have to trust God.
--Pope Francis, My Door is Always Open: a Conversation on Faith, Hope and the Church in a Time of Change
