Interesting That God had to show Peter the same 'dream' or vision 3 times.
Sometimes change can be really hard.

The apostles didn't want to be obedient to Acts 1:8... to go out into all the world...
So persecution came along and scattered the church... so that the Good News could be preached and listened to everywhere!

Change can just be so darn hard for us.
Sometimes we like to spiritualize topics instead of simply letting them out and dealing with them.

As I recall, not so long ago the clergy thought that the Word of God was far too sacred to be left in the common man's hand. They were dismayed at the idea of Bible's being put into the laity's hands.

What about drums in the church?
What about dancing, or media, etc?

What change is God trying to or-castrate in your life right now, that you might be resisting?
God is more interested in our character than our comfort... so obey before your 'house' gets turned upside down.

Acts 1:8 and Acts 10:15-16
