Mark 4:21-22 “21And he said to them, “Is a lamp brought in to be put under a basket, or under a bed, and not on a stand? 22For nothing is hidden except to be made manifest; nor is anything secret except to come to light.”
The following is commentary from Matthew Henry on the passage included above:
That those who are good ought to consider the obligations they are under to do good; that is, as in the parable before, to bring forth fruit. God expects a grateful return of his gifts to us, and a useful improvement of his gifts in us; for (v. 21), Is a candle brought to be put under a bushel, or under a bed? No, but that it may be set on a candlestick. The apostles were ordained, to receive the gospel, not for themselves only, but for the good of others, to communicate it to them. All Christians, as they have received the gift, must minister the same. Note, 1. Gifts and graces make a man as a candle; the candle of the Lord (Prov. 20:27), lighted by the Father of lights; the most eminent are but candles, poor lights, compared with the Sun of righteousness. A candle gives light but a little way, and but a little while, and is easily blown out, and continually burning down and wasting. 2. Many who are lighted as candles, put themselves under a bed, or under a bushel: they do not manifest grace themselves, nor minister grace to others; they have estates, and do no good with them; have their limbs and senses, wit and learning perhaps, but nobody is the better for them; they have spiritual gifts, but do not use them; like a taper in an urn, they burn to themselves. 3. Those who are lighted as candles, should set themselves on a candlestick; that is, should improve all opportunities of doing good, as those that were made for the glory of God, and the service of the communities they are members of; we are not born for ourselves.
The reason given for this, is, because there is nothing hid, which shall not be manifested, which should not be made manifest (so it might better be read), v. 22. There is no treasure of gifts and graces lodged in any but with design to be communicated; nor was the gospel made a secret to the apostles, to be concealed, but that it should come abroad, and be divulged to all the world. Though Christ expounded the parables to his disciples privately, yet it was with design to make them the more publicly useful; they were taught, that they might teach; and it is a general rule, that the ministration of the Spirit is given to every man to profit withal, not himself only, but others also.
