The crosses that we encounter each day are for our own good.  If it is a self-inflicted cross do to our own desires then it is because we are not following the plans of God.   Many people are suffering and it is difficult to ask these people to offer up there sufferings for the conversion of sinners or for another cause.  We must be open to the Holy Spirit in times of trial.  God is always with us and His mercy endures forever.  We should use our sufferings in a way that brings us closer to God.
