True Christianity versus False Christianity

This book talks about true Christianity, and the significant differences between different Christian churches regarding their validity when it comes to salvation. Jesus Christ foretold that in the end time false Christianity would be widespread and many people would be deceived by it. After Jesus told the disciples about the future destruction of the Temple, the disciples asked Him about these coming events. The disciples had asked Jesus two very important questions: What will be the sign of your coming, and What will be the sign of the end of the world? The word used for world in the original Greek was, Aion. Everyplace else in Scripture where the word Aion was used, it was translated as, age. So, the disciples were really asking Jesus, what will be the sign of your coming, and what will be the sign of the end of the age?
