Mark 4:21–23 (NKJV): 21 Also He said to them, “Is a lamp brought to be put under a basket or under a bed? Is it not to be set on a lampstand? 22 For there is nothing hidden which will not be revealed, nor has anything been kept secret but that it should come to light. 23 If anyone has ears to hear, let him hear.”
As this parable comes on the heels of the sower, the Lord seems to be making a connection between them. The true light of the gospel exposes all darkness and the quality of every man's faith as well as the fruit. Jesus was Himself the Light of the world (John 9:5), and He told us that we are the light of the world (Matt. 5:14). Our associating this light to only the good news of the gospel is somewhat myopic. In fact Jesus told His disciples in John 16:8, that when the Holy Spirit comes, He will convict the world of sin. The Lord is showing us through this parable that the light will reveal everything. Nothing hidden here will not be exposed. Ephesians 5:13–14 says, But all things that are exposed are made manifest by the light, for whatever makes manifest is light. Therefore He says:
“Awake, you who sleep,
Arise from the dead,
And Christ will give you light.”
We should be aware that God is light and in Him is no darkness at all (1 John 1:5), so when we are confronted with the marvelous light of the gospel of Christ, we must consider the depth of that righteousness and exactly what it has come to accomplish. He is quite interested in how we live and how we view His glorious light, the light that shines in darkness, even the deepest darkest regions of the heart. May we let the light of Christ illuminate our minds and hearts, and bring every sin to the throne of mercy.
