A television program that I enjoy watching has a segment called Ambush Makeover. Two women are chosen to undergo 3 hours of pampering to update their hair, makeup, and wardrobe. The change is often dramatic. 

When the women step from behind a curtain, the audience gasps. Friends and family members sometimes start to cry. After all of this, the person with the new look finally gets to see herself. Some are so shocked that they keep looking in the mirror as if to find proof that it’s really them.

As the women walk across the set to join their companions, the former self becomes evident. Most do not know how to walk in their new shoes. Although they look chic, their clumsy walk gives them away. Their transformation is incomplete.

This is true in our Christian lives as well. God does the work in us to give us a new start, but to walk in the way of the Lord (Deut. 11:22) requires time, effort, and lots of practice. If we just stand still and smile, we can pass as being transformed. But the way we walk tells how far along we are in living out that transformation. Being changed means giving up our previous way of life and learning a new way to walk (Rom. 6:4).

The new life in Christ has begun—
The past with its darkness is gone;
Look closer to see what the Savior has done,
For change is beginning to dawn. —Hess

A change in behavior begins with a change in the heart.
