Keeping your faith is a day to day challenge, brought on by the person's ability to balance a list of variables.
What are your fears?
What you need vs. what you want?
Do you really believe in what your following?
What is your self-esteem like?
Do you have friends, family, neighbors, that support you?
These questions are what your answer to your question rely on.
However, I would answer your question of what helps me keep my faith, with this simple word. "Friendship".
My friends have been there for me through every step of the way. Through every hard challenge in my life, sometime or another, I've relied on them for support, love, help, protection, advice, direction, ideas, etc.
A person is alone, and has no one to believe in him, if he/she doesn't have a friend 2 keep his/her 'FAITH' strong.
Ethel Smith, I hope that helps you answer your question.
