Who is Christ’s Family? (Matthew 12:46-13:9)

Christ’s immediate family desires to see him so they come to the house where Christ is teaching.  Christ does not seem all that receptive to their arrival, but rather launches into a teaching about the family of God.  Why does Christ delay in inviting them to come into the house?  Why does Christ then go on to speak about the parable of the sower?

Outsiders on the Inside (Matthew 8:1-17)

Matthew is writing a Gospel not just to confirm that Christ is the Messiah, but to call people to embrace the true Messiah in faith.  So, is this a Gospel that is merely rebuking the Israelites for not embracing their God?  Is this a Gospel that is excessive for one race?  Who can be an insider?
