Light exposes

The real self will be revealed
Luke 12:2-3) 2 For there is nothing covered, that shall not be revealed; neither hid, that shall not be known. 3 Therefore whatsoever ye have spoken in darkness shall be heard in the light; and that which ye have spoken in the ear in closets shall be proclaimed upon the housetops.
Your life is an open Book and can be more transparent than you want.

Thoughts and intentions exposed

Hebrews 4:12-13) 12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.13 Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.

God's word exposes our thoughts and intentions, nothing is hidden from God's searching eye, take time to read God's word and allow it to pierce your life and see the Great things God will do for you.
