On the night of September 13, 1935, a young Polish nun in Vilnius had a vision. She saw an angel preparing to strike the earth with bolts of lightning. She began to pray. The words that formed in her were unfamiliar: a new prayer, spoken over beads, offered to the Father through the wounds of Christ. The angel lowered his hand. The destruction stopped.
That nun was Sister Maria Faustina Kowalska. The prayer was the Chaplet of Divine Mercy. And over the years that followed, she recorded in her diary (Divine Mercy in My Soul) a series of promises that Jesus made to every soul willing to pray it.
These promises are not vague spiritual encouragements. They are specific, conditional, and in places almost staggering in their scope. The Church examined them. Saint John Paul II, who had devoted his life to the Divine Mercy devotion long before he became pope, canonized Faustina in the year 2000 and established the Feast of Divine Mercy for the universal Church. The promises stand.
Here is every one of them.
—
1. Protection from the enemy
“Whoever will recite it will receive great mercy at the hour of death.”
The chaplet is a prayer for life, but Jesus anchors its first promise in death. That hour, which every soul faces alone, is precisely where He pledges His presence. Whatever the enemy brings at the final moment, the soul that has prayed this chaplet is not undefended.
—
2. The rays that shield
The Divine Mercy image shows two rays streaming from Christ’s heart: one pale, one red. Jesus told Faustina these represent the water and blood from His pierced side: Baptism and the Eucharist, the two foundations of the Christian life. He promised that the soul sheltered beneath these rays would not perish. They are not decoration. They are armor.

3. The Feast of Mercy: complete remission
“I want to grant a complete pardon to the souls that will go to Confession and receive Holy Communion on the Feast of My Mercy.”
Mercy Sunday, the first Sunday after Easter, carries a grace the Church calls plenary: full remission of sin and punishment for those who receive the sacraments in a state of sincere conversion. Faustina recorded that Jesus called this day “the last hope of salvation” for souls who had grown cold. The chaplet belongs to that day as its heartbeat.
—
4. Grace for hardened sinners
“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.”
This is the promise that should stop every Catholic who has written off a family member, a friend, an enemy as beyond reach. Jesus says: once. One recitation of this chaplet, even by someone who has spent a lifetime in sin, opens a channel of grace. The mercy does not wait for the person to deserve it. It moves first.
—
5. For priests: supernatural power to convert
Jesus specifically addressed priests, promising that any confessor who recommends the chaplet to penitents would receive from Him an extraordinary power to bring hardened hearts back. The promise extends beyond spiritual directors. It belongs to anyone who places this prayer in another person’s hands.
—
6. Embraced by mercy: in life and at death
“The souls that say this chaplet will be embraced by My mercy during their lifetime and especially at the hour of their death.”
Two moments: the long stretch of ordinary life, and the final instant. Jesus promises His mercy across both. The chaplet does not only prepare a person for death. It shapes the whole shape of a life lived under mercy’s shelter.
—
7. Meeting the Merciful Savior, not the Judge
Those who spread devotion to Divine Mercy, Jesus told Faustina, will not stand before Him as Judge at the end. They will stand before Him as Merciful Savior. The distinction matters enormously. The same Christ judges and saves, but the posture in which a soul encounters Him is not fixed. It is shaped, in part, by whether that soul ran toward mercy or away from it.
—
8. The conversion of sinners
When the chaplet is prayed for the conversion of a sinner (any sinner, named or unnamed) Jesus promised that the prayer would always be answered. The answer may not look like what we expect. It may come at the final hour rather than the present one. But the request does not go unheard.
—
9. Mercy greater than all sin
“No soul that has approached Me has gone away unconsoled.”
This promise addresses not a practice but a fear: the fear that one has sinned too greatly, waited too long, wandered too far. Jesus explicitly rejected the idea that His mercy has a ceiling. Whatever has been done, the mercy is greater. The chaplet prayed with this trust is prayed at its deepest level.
—
10. The hour of three o’clock
“At three o’clock, implore My mercy especially for sinners; and, if only for a brief moment, immerse yourself in My Passion… This is the hour of great mercy for the whole world.”
Three in the afternoon is the Hour of Mercy, the moment Christ died on Calvary. Jesus asked that at this hour, wherever possible, the faithful pause and pray. The chaplet fits naturally here. So does a simple act of turning toward the crucifix. The hour itself carries a special opening of grace that the rest of the day does not.
—
11. You will obtain everything compatible with His will
“Through this chaplet you will obtain everything, if what you ask for is compatible with My will.”
This is one of the most direct promises in the whole of Faustina’s diary. It does not say you will receive comfortable answers or easy outcomes. It says that whatever aligns with His will, the chaplet can obtain. The qualifier is not a restriction. It is a guarantee that the prayer reaches the right place.
—
12. Peace for the dying
“I will fill their souls with peace, and the hour of their death will be a happy one.”
Jesus promised this specifically for hardened sinners who pray the chaplet. A happy death, in Catholic understanding, does not mean a painless one. It means a death in which the soul is at peace, reconciled, and ready. That gift, offered to the most resistant souls, is among the most tender promises in this entire list.
—
13. By the bedside of the dying
“When this chaplet is said by the bedside of a dying person, God’s anger is placated, unfathomable mercy envelops the soul, and the very depths of My tender mercy are moved for the sake of the sorrowful Passion of My Son.”
This is the promise for those who sit vigil. When a person is actively dying, the chaplet prayed aloud in that room does something specific and real. God’s justice is not circumvented. It is met, fully, by the intercession of Christ’s own Passion presented to the Father. The dying person need not even be conscious. The prayer works on their behalf.
—
14. Spreading the honor of mercy
The last promise is given to those who carry this devotion outward, who share it, teach it, place it in the hands of the grieving and the skeptical and the almost-lost. Jesus promised that He Himself would defend them before the Father. To spread the message of mercy is to take on a work He considers His own.
—
How to Begin
The chaplet is prayed on ordinary rosary beads. It opens with the Our Father, the Hail Mary, and the Apostles’ Creed. On each Our Father bead, the prayer is:
“Eternal Father, I offer You the Body and Blood, Soul and Divinity of Your dearly beloved Son, Our Lord Jesus Christ, in atonement for our sins and those of the whole world.”
On each Hail Mary bead:
“For the sake of His sorrowful Passion, have mercy on us and on the whole world.”
It closes with three repetitions of:
“Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and on the whole world.”
That is the whole prayer. It takes about five minutes. Jesus attached fourteen promises to it.

Saint Faustina died of tuberculosis in 1938, at thirty-three years old. She had spent her last years largely bedridden, writing. Her diary runs to nearly 700 pages. The chaplet she received is a single page. Pray it today.
Speak, in charity.
