The method of establishing perfect spiritual relationship with God that the Holy Quran teaches us is Islam, meaning devoting one's whole life to the … - Mirza Ghulam Ahmad

The charge advanced against me and my Jama‘at, that we do not believe in the Holy Prophet (pbuh) as the Seal of Prophets, is altogether false. The strength, certainty, comprehension and insight with which we acknowledge and believe in the Holy Prophet (pbuh) as the Seal of the Prophets, cannot even be dreamed of by the other Muslims; they do not have the capacity to comprehend the reality and the mystery comprised in the Seal of Prophethood. They have merely heard an expression from their ancestors but they are unaware of its import and do not know what it signifies and what is meant by believing in it. But we believe with full comprehension—and God Almighty knows this well—that the Holy Prophet (pbuh) is the Seal of the Prophets. God Almighty has disclosed the reality of the Seal of Prophethood in such a manner that we derive special delight from its contemplation which cannot be conceived of by anyone except those who have drunk deep at this fountain. We can illustrate the Seal of Prophethood by the example of the moon, which begins as a crescent and arrives at its perfection on the fourteenth night when it is called the full moon. In the same manner, the excellences of Prophethood reached their climax in the Holy Prophet (pbuh). Those who believe that Prophethood has been closed compulsorily and that the Holy Prophet (pbuh) should not be regarded as being superior even to the Prophet Jonas have not understood the reality of the Seal of Prophethood and do not have true knowledge of his superiority and excellences. Despite their own ignorance and lack of understanding, they charge us with denying the Seal of Prophethood. What shall I say concerning such invalids and how shall I express my pity for them!

The Holy Quran clearly forbids the use of force for the spread of the faith and directs its propagation through its inherent qualities and the good example of the Muslims. Do not be misled by the notion that in the beginning the Muslims were commanded to take up the sword. That sword was not taken up for the spread of the faith, but in self-defence against the enemies of Islam and for the purpose of establishing peace and security. It was no part of the purpose of taking it up to have recourse to coercion in the matter of faith".

Without doubt, a truly mighty and powerful person is not one who can move a mountain from its place, not in the least. True courage is to muster the strength to reform one's morals.
