True and Perfect God, to believe in Whom is essential for every person, is the Lord of all the worlds

The Promised Messiah 1835-1908 says:

Impossible as it is, yet by way of argument let us assume that Jesus (peace be upon him) did claim to be God. In that case, for him to confine his beneficence to such a small circle as the House of Israel does not behove the magnanimity of God. Had he been God, was he God only for the House of Israel to the exclusion of all other nations? He is known to have suggested that he had no concern for those who did not belong to the House of Israel.

In short, the Jews and the Christians do believe that all Prophets and Messengers have been appearing from among them, and that Divine scriptures were revealed to them alone. Thereafter, according to the beliefs of the Christians, the institution of revelation and communion with God ended with Jesus Christ (peace be upon him) as though a seal had been set on the institution of revelation from God.

Unfortunately the Hindus of the Arya sect also entertain a similar belief. Like the Jews and Christians, who restrict the institution of Prophethood and Divine revelation exclusively to their people and deny the honour of Divine revelation to others, the Aryas also, unfortunately for the human race, have adopted the same doctrine. They too believe that the blessing of Divine communication was never bestowed to any people outside the domain of the Aryan race. Again it is India alone which, according to them, is exclusively blessed by God for the selection of the four ‘Rishis’ from its soil; it is Sanskrit alone, the language of the Vedas, which has always been the medium of instruction chosen by God. One can safely conclude from this, that both these nations do not consider God to be the Lord [Provident] of all the worlds.

Notwithstanding this, He is still proclaimed to be Lord of the Universe and not that of the Israelites or the Aryans alone. Moreover this strange behaviour of God, as presented by them, draws an image of God which is so partial that He appears unmindful of the rest of His creation. Thus, it is for the refutation of such erroneous views, that God commences the Holy Qur’an with the verse:

The Holy Quran : Chapter 1: Al-Fatihah
[1:2] All praise belongs to Allah, Lord of all the worlds,

God also made it clear in several places in the Holy Qur’an that His Messengers have been appearing in different lands all over the world.

In fact He did not neglect any people or any country. The Holy Qur’an explains through various examples that just as God has been looking after the physical development of the people of every country, in accordance with their requirements, so has He blessed every country and every people with spiritual upbringing. Allah says in the Holy Qur’an:

The Holy Quran : Chapter 35: Al-Fatir
[35:25] Verily, We have sent thee with the Truth, as a bearer of glad tidings and as a Warner; and there is no people to whom a Warner has not been sent.

Meaning that there is no people to whom a Warner has not been sent.

Therefore there is no question that the True and Perfect God, to believe in Whom is essential for every person, is the Lord of all the worlds. Furthermore, His providence is not confined to any particular people, age or country. In fact, He is the Lord of all peoples, the Lord of time and space, and He is the Sovereign of all the countries. He alone is the 5. All praise belongs to Allah, Lord of all the worlds.
Fountainhead of all beneficence and the Source of every physical and spiritual strength. All that exists is sustained by Him. He is the Support for every creature.

It is the universal beneficence of God which encompasses all peoples, all countries and all ages. It so happened lest anyone should have cause to complain that: ‘God has bestowed His favour upon such and such people, but not upon us.’ Or that: ‘So and so received the Book in order to be guided while we did not.’ Or that: ‘In such and such an age, He revealed Himself through His revelations, communications and miracles but in our time He remained hidden.’ Thus, by demonstrating His universal beneficence, He left no justification for such possible accusations. He displayed His virtues boundlessly so that no people remain bereft of physical and spiritual bounties from Him. He also did not treat any age as doomed.

So, when such are the attributes of our Lord, it is but befitting for us to acquire them ourselves. So, O compatriots!

This short epistle entitled A Message of Peace is being presented to you with all due respects and with a sincere heartfelt prayer that Almighty God may Himself inspire you and fill your hearts with trust in my sincerity, lest you misread this friendly gesture and consider it to be an attempt to gain some ulterior motive. Dear Countrymen! The matter of the Hereafter is very often obscured to ordinary people. Its secrets are known only to a few of the enlightened, who embrace a kind of death [for the sake of their Lord] before they actually die. The goodness of this world, on the other hand, is easily recognized by any man with vision and wisdom.
