The Divine Mercy And The Sacred Heart Of Jesus

This from Mark Mallett's blog. Mark is Catholic lay evangelist from Canada.

THE "END TIME" DEVOTIONS
While the revelations of the merciful Heart of Jesus to St. Margaret Mary Alacoque (1647-1690 A.D.) and St. Faustina Kowalska (1905-1938) were separated by three centuries, they have a common theme: devotion to the Heart of Jesus will be a sign of the end times.

I understood that devotion to the Sacred Heart is a last effort of His Love towards Christians of these latter times, by proposing to them an object and means so calculated to persuade them to love Him. —St. Margaret Mary, Antichrist and the End Times, Fr. Joseph Iannuzzi, p. 65

This devotion was the last effort of His love that He would grant to men in these latter ages, in order to withdraw from the empire of Satan which He desired to destroy, and thus to introduce them into the sweet liberty of the rule of His love, which He wished to restore in the hearts of all those who should embrace this devotion. —St. Margaret Mary, http://www.sacredheartdevotion.com/
Jesus appeared to St. Faustina with rays of light pouring from His Merciful Heart. From her Diary:

I am prolonging the time of mercy for the sake of [sinners]…. While there is
still time, let them have recourse to the fount of My mercy… He who refuses to
pass through the door of My mercy must pass through the door of My justice.
—Diary of St Faustina, 1160, 848, 1146

And recall again the words of St. John Bosco in his famous dream of the two pillars:

There will be chaos in the Church. Tranquility will not return until the Pope succeeds in anchoring the boat of Peter between the Twin Pillars of Eucharistic devotion and devotion to Our Lady. —Forty Dreams of St. John Bosco, compiled and edited by Fr. J. Bacchiarello, S.D.B.

The call to the Bastion is a call to look to the Eucharist, which is the Sacred Heart of Jesus. To entrust our whole beings to Him who is our refuge. We now see these devotions to His Heart converging in our times.
The call, then, is to prepare for the end of this age.
