>You have no forgiveness of sin because you reject the sacrifice We believe firmly that God doesn't need permission or causality to forgive your sins, or really to do anything at all. He says "be" and "it is". God does not need to "die" or have a "begotten son" in order to forgive you for your shortcomings. He is the most gracious, the most merciful. He does whatever He wills. >origin is pagan and muslims worship the black cube that was absolutely a pagan idol We believe firmly that Muhammad sallahu alayhi wasalam was born in the city where the first temple to God all mighty was constructed. We believe firmly that this first temple to the one true God and creator of the universe was located exactly where the masjid/temple stands today in Mecca/Becca called the Kaaba. Before praying to this "black cube" Muhammad sallahu alayhi wasalam had Muslims pray towards Jerusalem. The black covering was not always on the Kaaba, and we know that the Kaaba was originally rectangular before it was rebuilt. One prayer inside of this small masjid is worth 100,000 prayers in any other masjid. Muhammad sallahu alayhi wasalam was responsible for cleansing this temple of all stone idols. He was sent to a very pagan people with some Christians and Jews as well. You should read the 3rd chapter of the Quran, named after the father of the Virgin Mary, Imran. We Muslims believe that Jesus (sallahu alayhi wasalam) and Mary are the only two humans to have NOT been touched by the devil at birth. This chapter will explain the truth of what happened to Jesus, with a clear explanation: https://quran.com/3 And this is the chapter of the Quran about Mary the mother of Jesus: https://quran.com/19
