Always ask for mercy. The devotion functions inter alia to proclaim the
mercy of God. That God is infinitely merciful, hence sinners no matter how
terrible should return in total trust to the merciful embrace of the Father.
Mankind should ceaselessly beg for God’s mercy.

The devotion has a duty to implore God’s Mercy upon humanity especially sinners through the prayer Jesus thought to St. Maria Faustina, the Divine mercy prayers.

Those who embrace the devotion will not pass through God’s judgment
after death but through the door of His mercy. Those who refuse to
embrace it will pass through the door of justice.

Be merciful to people especially devotes are recipients of God’s
unfathomable mercy should be give out mercy by being merciful to fellow
humans “for blessed are the merciful for they shall obtain mercy” (Mt 5:7).
C – Complete trust, humanity must have trust in God’s mercy for salvation.
God’s mercy as Jesus told St. Maria Faustina is unfathomable, it is like a
ocean which its length, breath and depth cannot be measured. It exits for
sinful mankind to enter with trust for pardon and mercy. There is no sin
too grievous to be forgiven by God so long as there is genuine repentance
and resolve on the part of penitent to amend his life. There is hope for
even the worst sinner if only he can repent today before it is too late for
God’s mercy patiently awaits every sinner.

The devotion proclaims the mercy of God to the world, implores His mercy
for the whole world especially for sinners and let’s humanity experience
God’s mercy through the spiritual and corporal works of mercy.
The Devotion is for all humanity, Catholics, non-Catholics, Muslims e.t.c
