What are the best ways to convince Christians to embrace Islam, and is reading the Gospel and understanding the interpretation of the Qur'an and the stories of the prophets sufficient for that?

Inviting non-Muslims to Islam requires significant effort. The caller to Islam must be well-versed in his religion, knowledgeable about misconceptions, and capable of refuting them. Additionally, he must be aware of the flaws in other religions, because inadequate preparation can lead to defeat or temptation. It is recommended to read books such as "Qadha'if al-Haqq" by Al-Ghazali, "Hidayat al-Hayara" by Ibn al-Qayyim, "Izhar al-Haqq" by Al-Dehlawi, and "Al-Jawab al-Sahih (definition)" by Ibn Taymiyyah, and to listen to the debates of Sheikh Ahmed Deedat.
