Changing our Minds

In worship last Sunday, Terry asked us what God had changed our mind about.  The sermon was based on John 3:1-17. - Nicodemus meets with Jesus at night to ask questions.  Terry's assumption had always been that Nicodemus' mind had been changed by the conversation, but a source she read in preparation for the sermon suggested that we don't know that for certain.

Nicodemus goes to prepare Jesus' body after the crucifixion with many spices and plans.  The writer of the source said that if Nicodemus' mind had been changed by his conversation with Jesus, maybe he wouldn't have taken the spices to the tomb.

Interesting thought.

But what interested me more was the idea and possibilities of allowing God to change our minds. We talk often about God changing our hearts, but do we ever open our minds enough to allow God to change them?  

Or are out minds made up, no matter what - even concerning matters of faith.  It seems to me that allow God to change our minds about those things is often the hardest - and yet God would be the authority, right?

When has God last changed your mind?
