Pray the Divine Mercy Chaplet with Andi Pineda Compton and Stephanie Fries. 

“Say unceasingly the Chaplet that I have taught you. Whoever will recite it, they will receive great mercy at the hour of death. Priests will recommend it to sinners as their last hope of salvation. Even if there were a sinner most hardened, if he were to recite this chaplet only once, he would receive grace from My infinite mercy.” (Diary, 687)
