God sees everything you do. He loves you no matter what and understands when you struggle. Hiding things from people is a form of bondage. We hide things out of fear they will be taken away, shame, disobedience, or selfishness.
You are free, if you choose to be. Imagine holding nothing tightly because you trusted God to provide for all your needs. Imagine never lying to hide the truth or worrying about being caught.
This is an element of the peace that surpasses all understanding. Think of the energy you could save for something else, if you hid nothing.
