Prayer to St Joseph, for a happy death

O Glorious St. Joseph, behold I choose thee today for my special patron in life and at the hour of my death.
Preserve and increase in me the spirit of prayer and fervor in the service of God.
Remove far from me every kind of sin; obtain for me that my death may not come upon me unawares, but that I may have time to confess my sins sacramentally and to bewail them with a most perfect understanding and a most sincere and perfect contrition, in order that I may breathe forth my soul into the hands of Jesus and Mary. 
Amen.
