Jesus Christ suffered and died on the cross for the sins of mankind.   We all suffer in some way. Many people have physical sufferings and many have mental sufferings.  Christ offered His sufferings for the salvation of the world and we too can offer our sufferings up for others.  Having physical pains or mental anguish is difficult for many but if we can keep a Christian prospective on our sufferings, these suffering no matter how difficult can lead us to God and to heaven one day.   If we offer these sufferings up to the world and for the conversions of sinners many great things are possible.  Once this is done the devil will back down and the chance of dispair fades away because we unite our sufferings with Christ sufferings on the cross.
