Luke 8:16-18

And no man, when he hath lighted a lamp, covereth it with a vessel, or putteth it under a bed; but putteth it on a stand, that they that enter in may see the light. For nothing is hid, that shall not be made manifest; nor anything secret, that shall not be known and come to light. Take heed therefore how ye hear: for whosoever hath, to him shall be given; and whosoever hath not, from him shall be taken away even that which he thinketh he hath.
