Take Heed How You Hear

Luke 8:16-21
No man, when he hath lighted a candle, covereth it with a vessel, or putteth it under a bed; but setteth it on a candlestick, that they which enter in may see the light.
17 For nothing is secret, that shall not be made manifest; neither any thing hid, that shall not be known and come abroad.
18 Take heed therefore how ye hear: for whosoever hath, to him shall be given; and whosoever hath not, from him shall be taken even that which he seemeth to have.
19 Then came to him his mother and his brethren, and could not come at him for the press.
20 And it was told him by certain which said, Thy mother and thy brethren stand without, desiring to see thee.
21 And he answered and said unto them, My mother and my brethren are these which hear the word of God, and do it.
