You have it or not and it grows

Would you agree with me.  One either has faith or they don't.  You believe or you don't.  It's like you are pregnant or not.  Love however; seems to be a continued growth.  Each day I learn to love more and when I feel like I've reached my max, I still can love even more.  What are you thoughts, are continually challenged to find even more love in your heart, more compassion, more empathy?
