HonestMuslim is a resource for learning about issues in the Quran, Hadiths, Sunnah, and also the misconceptions that Muslims have about Jews & Christianity. It targets two different audiences:
For Muslims
The Quran gives the following as a test to confirm its authenticity. If there are no inconsistencies, then it is actually from Allah:
Quran 4:82
Do they not then reflect on the Quran? Had it been from anyone other than Allah, they would have certainly found in it many inconsistencies.
The problem with this is that there are many inconsistencies as explored in the issue page below. These are made to help you to bring you back to worshipping the one true God existing as three persons - The Father, The Son (Jesus Christ), and the Holy Spirit.
For Christians
This site is a resource that you can use during your ministry to Muslims. Learn about the issues within Islam, and responses to common misconceptions that Muslims have regarding Christianity.
