The Church's nature makes her easy to find, but extrinsic factors can make her difficult to find. Plainly put, the ease with which one finds the Church has lots to do with WHERE the Church is physically/geographically. Tell the millions of American Indians at any time prior to the sixteenth century the Church is 'easy to find.' Sure, for Europeans. There are times/places in history where at least for some people, the Church is difficult to find.
