21 And he said to them, Does the lamp come that it should be put under the bushel or under the couch? [Is it] not that it should be set upon the lamp-stand? 22 For there is nothing hidden which shall not be made manifest; nor does any secret thing take place, but that it should come to light. 23 If any one have ears to hear, let him hear. 24 And he said to them, Take heed what ye hear; with what measure ye mete, it shall be meted to you; and there shall be [more] added to you. 25 For whosoever has, to him shall be given; and he who has not, even what he has shall be taken from him.
Matthew Henry's Commentary on Mark 4:21-25
Commentary on Mark 4:21-34
(Read Mark 4:21-34)
These declarations were intended to call the attention of the disciples to the word of Christ. By his thus instructing them, they were made able to instruct others; as candles are lighted, not to be covered, but to be placed on a candlestick, that they may give light to a room. This parable of the good seed, shows the manner in which the kingdom of God makes progress in the world. Let but the word of Christ have the place it ought to have in a soul, and it will show itself in a good conversation. It grows gradually: first the blade; then the ear; after that the full corn in the ear. When it is sprung up, it will go forward. The work of grace in the soul is, at first, but the day of small things; yet it has mighty products even now, while it is in its growth; but what will there be when it is perfected in heaven!
