Christianity may appear complicated if you consider the plethora of teachings online, in churches, through seminars, conferences, and more.  You may even discover teachings that contradict each others from various ministers.  You may find your head spinning trying to keep up with all of the guidelines and mandates from those teachings.  However, Christianity is very simple.  Christianity is about Jesus Christ and what he did for us.  He died on the cross, rose from the dead, and ascended to the Father.
