Souls who spread the honour of My mercy I shield through their entire lives as a tender mother her infant, and at the hour of death I will not be a Judge for them, but the Merciful Saviour (Diary 1075). This is what the Lord Jesus promised to everyone who will proclaim His Mercy, spread its honour in any way. Priests can rejoice at His additional promise: Hardened sinners will repent on hearing their words when they speak about My unfathomable mercy, about the compassion I have for them in My Heart. To priests who proclaim and extol My mercy, I will give wondrous power; I will anoint their words and touch the hearts of those to whom they will speak (Diary 1521). These promises show how important it is to spread the honour of the Divine Mercy since Jesus promises His maternal care, during the lifetime and at the hour of death, to everyone who will undertake this task. Therefore, apart from the Image, Feast, Chaplet and Hour of Mercy, spreading honour of the Divine Mercy is also a form of the Devotion, because Jesus also attached promises to it and the promises pertain to all people.
Spreading honour of the Mercy, that is, proclaiming the mystery of the Divine Mercy, most fully revealed in the crucified and risen Christ, by the testimony of life, deeds, words and prayer is not only to show the road to a beautiful and happy life on earth but also, and maybe first of all, it is to serve the work of salvation and sanctification of the world as well as it is to prepare humanity for Christ’s second coming to earth: The Lord Jesus said to Sister Faustina: Secretary of My mercy, write, tell souls about this great mercy of Mine, because the awful day, the day of My justice, is near (Diary 965). Do not tire of proclaiming My mercy (Diary 1521). Tell the whole world about My inconceivable mercy (Diary 699). Let all mankind recognize My unfathomable mercy. It is a sign for the end times; after it will come the day of justice (Diary 848). Write: before I come as a just Judge, I first open wide the door of My mercy. He who refuses to pass through the door of My mercy must pass through the door of My justice (Diary 1146). Therefore, the Lord Jesus’ urgent call directed to Sister Faustina and, through her, to the entire Church and the whole world, can be found so many times in the ‚Diary’.
The task of preaching the message of Mercy arises from the gift recei- ved as early as during the Sacrament of Holy Baptism. It is also a right and duty of the Church and, thus, of all the faithful. In 2002 Holy Father John Paul II said in Błonia Park in Cracow: The hour has come when the message of Divine Mercy is able to fill hearts with hope and to become the spark of a new civilization: the civilization of love.
