As Christians we are instructed in the Word of God to not be "a respecters of people", but peer pressure and fear of people can drive as away from a Christ centered life. When People are Big and God is Small is a excellent study for anyone to guard against peer pressure.
A perfect suggested reading for teens.
The focus of the book is to how a healthy fear of God will result in people having less control and power over our lives.
Some of the helpful points are:
1. Time spent with God will reduced our fear of "what others may think".
2. Jesus did not try to be a people-pleaser.
3. Choosing to please people rather than God is idolatry.
4. When we fear God we stop putting our own needs first.
5. We can learn to love people more; while we learn to need them less (only God can truly provide our needs).
