There are numerous contradictions in the bible, would that constitute as proof?

There no serious contradictions in the four Gospels, although they were written by four different people in three different languages (Matthew and John wrote in Hebrew, Mark in Latin and Luke in Greek) so there's bound to be some minor differences. Matthew and John were disciples, while Mark and Luke were not.

Different authors give different emphasis to the three core beliefs in Christianity - faith, works and love. For example John consistently emphasized love while Paul more often emphasized faith. Yet in I Corinthians 13 Paul acknowledges that love is greater than faith.
