This is an amazing lesson for all preachers.. It is not a matter to convince minds, but to penetrate the hearts, apart from all interruptions of daily hectic life.. How to simply communicate and establish a consensus, which everyone has it already in the depth of the heart..
Maybe I do not care much of her conversion to Islam, because this is a secondary issue.. It is all about delivering the message of Oneness or Tawheed; which every persons feels deeply inside their hearts.. People may been raised to exercise Polytheism; yet when they pray and supplicate, they address the One God.. Many are confused, misled and illiterate, yet their concept of Oneness is uneasy to explain.. Therefore, the loving preaching is the most critical for all, for every religion, for both believers and non-believers..
Quran says that seeds of believe is there within each one’s heart..
وَإِذْ أَخَذَ رَبُّكَ مِن بَنِي آدَمَ مِن ظُهُورِهِمْ ذُرِّيَّتَهُمْ وَأَشْهَدَهُمْ عَلَىٰ أَنفُسِهِمْ أَلَسْتُ بِرَبِّكُمْ ۖ قَالُوا بَلَىٰ ۛ شَهِدْنَا ۛ أَن تَقُولُوا يَوْمَ الْقِيَامَةِ إِنَّا كُنَّا عَنْ هَٰذَا غَافِلِينَ
When thy Lord drew forth from the Children of Adam – from their loins – their descendants, and made them testify concerning themselves, (saying): “Am I not your Lord (who cherishes and sustains you)?”- They said: “Yea! We do testify!” (This), lest ye should say on the Day of Judgment: “Of this we were never mindful”
(7/172) Translated by Yousuf Ali
When thy Lord had materialized the seeds of Adam’s descendants from their own spinals; Making them observing their own creation; Stating: I am your Lord? They admitted Yea! We shall testify on the Day of Judgment how we were unmindful

Also, Rasoul Allah PBUH had confirmed that every child is born on the instinct belief of Oneness; only his parents and society name and raise his religion..
By default, all religions need to consolidate their followers rather than preaching for conversions.. One of the notable early Clerks had called to abandon reproducing if chaotic times spread.. There is no use of masses of followers if the substance became poor.. Therefore, I emphasis on his soft approach and calm leadership, which everyone should learn.. for life, for business and for religion as well.. It cost nothing, but fitness to be a human with clear loving heart..
