Unfortunately Christians today are not following Jesus (PBUH) but they were deceived and derailed from Jesus path by his bitterest enemy rabbi Paul! The most accurate human written account is that of Barnabas; the closest disciple of Jesus. However Barnabas was banned by followers of Paul who also killed numerous true followers of Jesus ( Ref: Blood on the cross by Ahmad Thompson)!
Today we are fortunate that the God all mighty Who saved Jesus from crucification also save his life and message in the final ever preserved ever fresh divine book Quran. I invite all Christians and Jews to study Quran unbiased as it is indeed the most precious gift the God which can solve all individual and collective problems and rescue you from all sorts of slavery!
