Before birth God assigns to every man the species, sex, family, and nation to which s/he will be given. These assigned identities can never be truly revoked. In this case we are dealing specifically with the nation and to a lesser extent; the family. Since God has pre-selected for us our nation it is our responsibility to love what God has chosen. To express our appreciation, beyond prayer, would be to love one's nation, the people who built it, the land which sustains it, and the culture which had sprung forth from it.
Reading that is going to give a liberal a headache, as the emphasis here is not on self-chosen identity but on appreciating an identity we are assigned by God - an identity that is so part of us that it cannot be wholly abandoned.
Ruskin argues, tellingly I believe, that we express our appreciation for what God has chosen by acting on our responsibility to love our nation, our forebears, and the land and culture to which we are connected.
