What a tough question. It always bothers me when someone starts talking about being called to a higher level of holiness. I think I know what they mean when the say it but what I often hear is that I'm going to start earning my salvation better than I am now.
Obviously we are called to please God and there are things that scripture makes clear are required, but I always find myself going to Galations for a balanced perspective.
Galatians 3:1 - 5 (NIV) 1You foolish Galatians! Who has bewitched you? Before your very eyes Jesus Christ was clearly portrayed as crucified. 2I would like to learn just one thing from you: Did you receive the Spirit by observing the law, or by believing what you heard? 3Are you so foolish? After beginning with the Spirit, are you now trying to attain your goal by human effort? 4Have you suffered so much for nothing—if it really was for nothing? 5Does God give you his Spirit and work miracles among you because you observe the law, or because you believe what you heard?
The question here is "What is holiness?" Is it doing ANYTHING different? or is it the condition we find ourselves in after experiencing Christ?
If Christ by his Holy Spirit has taken up residence in us then there will be visible, genuine changes in our life evidenced by both word and deed. But the changes are not holiness... holiness entered us when the Spirit of God entered us.
Isaiah 61:10 I delight greatly in the LORD;
my soul rejoices in my God.
For he has clothed me with garments of salvation
and arrayed me in a robe of righteousness,
