Divine Mercy prayer card (wallet size, Vilnius)

Prayer on back:

O greatly Merciful God, Infinite Goodness,
today all mankind calls out from the
abyss of its misery to Your mercy, to Your
compassion, O God; and it is with its mighty
voice of misery that it cries out. Gracious God,
do not reject the prayer of this earth's exiles! O
Lord, Goodness beyond our understanding,
Who are acquainted with our misery through
and through, and know that by our own
power we cannot ascend to You, we implore
You: anticipate us with Your grace and keep
on increasing Your mercy in us, that we may
faithfully do Your holy will all through our life
and at death's hour. Let the omnipotence of
Your mercy shield us from the darts of our
salvation's enemies, that we may with confidence,
as Your children, await Your final
coming, that day known to You alone. And
we expect to obtain everything promised us
by Jesus in spite of all our wretchedness. For
Jesus is our Hope: Through His merciful Heart
as through an open gate we pass through to
heaven (Diary of St. Faustina Kowalska, 1570).
