When Jesus talked about taking up our crosses, he was not talking about enduring illness. In the context, he warns about loving family members more than him. If you have never had a family member discourage you from exercising or talking about your Christian values, then you are very fortunate. Being part of a family creates a kind of unspoken obligation. Family members can use the natural obligation of respect to impose non-Christian values on you. Because this imposition comes from a family member, it can be painful and difficult to stand up for your faith. Standing up and the difficulties that arise because of it are the cross that we must bear as followers of Christ.
