What is the importance of reading the Bible? I have heard many pastors encouraging their members to read the Bible daily.

Why do we have to read the Bible daily?

Is going to church and listening to sermons not enough?
The Sadducees posted a question on Christianity.SE about married life after resurrection (they didn't believe in resurrection of the dead) and Jesus replied (Matthew 22:29):


  But Jesus answered them, “You are wrong, because you know neither the Scriptures nor the power of God.


Reading the bible == knowing the scriptures helps us to prevent developing erroneous views that hinder our spiritual growth or potentially lead us astray. Sometimes even preachers from the pulpit preach doctrines that have errors or even heresies in them and though the preachers responsibility is greater, the listener is not without one.
