A good test of the value of any given religious belief is how it impacts your actions. Does this belief make you a better person? Does it make you kinder, more generous, more understanding, more dedicated to creating a fair and just society for both people like and unlike you? Or, does this belief make you more judgmental, tighter-fisted, narrower of vision, and cause you to only value people exactly like you?
Have you explored the impacts of this belief on others through their eyes and listened to what people who do not share this belief have to say about how it effects them?
A good test of the value of any given religious observance is, were you to find out later beyond a shadow of a doubt that the underlying specific theological claims were not literally true, would you be upset to have lived a religious life the way you did? Or would you still value the time spent in prayer, in study, in ritual, in meditation, in community?
Does your faith and/or the texts it is based on have to be literally true for it to still carry meaning for you?
A good test for the the validity of any given religious intuition is what it encourages you to do. Does this spiritual experience move you to examine yourself carefully and work to be a better person and to better society? Or does it move you to seek to serve your own interests, even if it wears the sheen of piety?
Do you truly believe that G-d would ask you to harm other people, other beings, or the environment, or is that your yetzer hara talking instead? Is that a G-d you would even find worthy of worship?
