Luke 8:15-18 (KJV)
15 But that on the good ground are they, which in an honest and good heart, having heard the word, keep it, and bring forth fruit with patience.
16 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.
Luke 8:11-13 (KJV)
11 Now the parable is this: The seed is the word of God.
12 Those by the way side are they that hear; then cometh the devil, and taketh away the word out of their hearts, lest they should believe and be saved.
13 They on the rock are they, which, when they hear, receive the word with joy; and these have no root, which for a while believe, and in time of temptation fall away.
