Allow your sufferings to be washed in the Precious Blood of Jesus that flows from Calvary's hill (and climb this very hill in imitation of Our Beloved, and there, lay your sorrow down on the ground before His feet). Lay it all down, every last bit of it. Give it all to Christ and Our Lady. Offer these sufferings for the conversion of sinners and the Glory of God.
Now that the body is failing, strive more than ever to be in the state of Grace as to protect the precious life of the eternal soul.
