The Parable of the Lamp and the Growing Seed (Mark 4:21-29)
What do we truly want? We want to know. Everyone has their own fields of interest. Stocks, employment, sales, tourist attractions, and restaurants are common interests for many. However, God is the source of all knowledge (Proverbs 2:6). Furthermore, God delights in making things known to us (James 1:5; Colossians 1:9-10). What God gives us is the truth.
In Mark 4:21-29, Jesus tells the Parable of the Lamp and the Parable of the Growing Seed. Here, He teaches the secret of what the Word of God is and how the sown Word grows.
A Lamp on a Stand (Luke 8:16-18)
21 He said to them, “Do you bring in a lamp to put it under a bowl or a bed? Instead, don’t you put it on its stand? 22 For whatever is hidden is meant to be disclosed, and whatever is concealed is meant to be brought out into the open. 23 If anyone has ears to hear, let them hear.” (Mark 4:21-23)
The Parable of the Lamp reveals the role of God’s Word. God is light, and His Word is a lamp. The Word of God is the key that unlocks the secrets of the Kingdom of God. These secrets include the secrets of humanity, evil, Christ, redemption, and bearing fruit.
It reveals where humans come from and where we are going; how we fell and how we reach salvation; how we grow; why pain and suffering continue; why there is a gap between our desires and reality; and what the true hope of humanity is.
Furthermore, it reveals how God created man, how and why He saves fallen man, how He loves us, why He refines us, and for what purpose He allows hardship and pain. Above all, it reveals the heavenly inheritance God has given to those who believe.
The Word of God is a lamp. A lamp is not intended to be hidden under a bed, but to be placed on a stand. A lamp illuminates dark places. God’s light fills all creation (Genesis 1:14). By day the sun shines, and by night the moon—reflecting the sun—shines over the darkness. The sky is filled with countless stars that embroider the dark night.
Therefore, nothing can be hidden or concealed before God. Everything is laid bare before Him.
13 Nothing in all creation is hidden from God’s sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account. (Hebrews 4:13)
God observes all things with eyes like blazing fire, and He knows the hearts of all people (Revelation 2:18; John 2:24-25). God shines His holy light into the human heart.
People think they can hide things, but they cannot. There is a Korean proverb that says, "Birds hear the words spoken by day, and mice hear the words spoken by night." It means there are no secrets in this world. How much more is it true that nothing can be hidden from the Creator God who made all things?
2 There is nothing concealed that will not be disclosed, or hidden that will not be made known. 3 What you have said in the dark will be heard in the daylight, and what you have whispered in the ear in the inner rooms will be proclaimed from the roofs. (Luke 12:2-3)
How Does God Speak?
God reveals His divine power and glory through His creation and through our bodies (Romans 1:19). God also reveals His grace and kindness through the hardships, pain, and sorrows of life (Isaiah 30:20-21; 1 Peter 4:12). The pain and suffering that everyone experiences is an expression and evidence of God’s holy love (Hebrews 12:6). He reveals His holy glory even through disasters like floods and through wars.
Most importantly, Christ who dwells within us guides, teaches, and protects us (Colossians 1:27). God sends the Spirit of truth, the Holy Spirit, into us; He gives us the power to obey by faith and pours out the grace to repent and turn back to Him. Also, when we open the Bible to read and meditate, He pours out the grace of understanding and inspiration.
Therefore, anyone can believe in and rely on God, who is present throughout all creation, and place their hope in the Lord (Psalm 19:1; Ephesians 1:23). God dwells in the hearts of believers, guiding, leading, and protecting them daily through His Word. Although we face tribulations in this world, we hope for the Kingdom of Heaven, which God has given as a promise.
16 Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. 17 For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. 18 So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal. (2 Corinthians 4:16-18)
The Secret of Growth: Hearing and Obeying
"Consider carefully what you hear," he continued. "With the measure you use, it will be measured to you—and even more. Whoever has will be given more; whoever does not have, even what they have will be taken from them." (Mark 4:24-25)
Humans are constantly listening. As children, we listen to our parents; in school, we listen to teachers. We even listen to the internal monologue within ourselves. However, not everything we hear is the truth. In particular, there is the whispering voice of the devil—the "ruler of the kingdom of the air" and the father of lies (Ephesians 2:2). The devil’s voice isn't always a 100% lie; it is often cleverly mixed with truth (Genesis 3:1).
Just like the spam mixed into our daily emails and texts, falsehoods are blended into our lives. If we listen poorly, we face ruin. Therefore, we must discern what we hear. This is God’s holy promise: those who hear, receive, and obey the word of God’s truth will produce a crop—thirty, sixty, or even a hundred times what was sown (Mark 4:8, 20).
Those who obey God’s Word engrave that truth deep in their hearts as a heavenly blessing. Abraham, who moved to Canaan in faithful obedience, experienced and believed in God as his "shield" and "very great reward" (Genesis 15:1). We cannot obey by knowing every outcome; we do it by faith. Consequently, obedience strengthens that faith, making it deeper and higher.
This is why those who obey by faith continue to receive "measure" (understanding). Conversely, those who lack faith and do not obey lose even what they have. This is the secret of growing in Christ: without obedience, you cannot truly grasp the truth.
God showed us the ultimate model of obedience through His Son. Jesus gave His life to obey the Father’s will (Philippians 2:8). Obedience involves risk. Abraham moved to Canaan, a place where he had nothing to rely on, simply because he believed and obeyed God's promise.
God is eternal. In Him are hidden all the treasures of eternal wisdom and knowledge (Romans 11:33; Colossians 2:3). We are called to a holy journey of discovering these treasures. While this journey is filled with challenges, we do not walk it alone. Jesus Christ, who did not spare His own life for us, is always with us (Matthew 28:20; Romans 8:32).
The Parable of the Growing Seed
He also said, "This is what the kingdom of God is like. A man scatters seed on the ground. Night and day, whether he sleeps or gets up, the seed sprouts and grows, though he does not know how. All by itself the soil produces grain—first the stalk, then the head, then the full kernel in the head. As soon as the grain is ripe, he puts the sickle to it, because the harvest has come." (Mark 4:26-29)
The Parable of the Growing Seed reveals a growth process that is invisible to the eye. The Kingdom of God is like the Son of Man sowing seed in the field of the human heart. The seed grows, but we cannot see how it happens. In reality, for a seed to grow, it must first fall to the ground and "die" (John 12:24). It seems dead and buried, but from there, the sprout, the head, and finally the fruit emerge.
While the preparation happens underground, the sprout and the grain eventually become visible markers of growth. Christians may not have a physical "sign" of growth, but the evidence appears as we become more like Christ.
As the years pass in Christ, we find ourselves becoming:
- Less: Angry, shocked, anxious, resentful, and envious.
- More: Forgiving, loving, thankful, hopeful, and compassionate.
We begin to forgive even those who are hard to love. Instead of demanding our rights, we learn to yield and let go. Why? Because Christ loved us that way (Romans 5:8) and because we know our reward is not on this earth, but stored in heaven (1 Peter 1:3-4).
The process of "dying to self," like a seed rotting in the earth, is difficult. It feels like moving a mountain (Matthew 17:20). But for a follower of Jesus, this is not an option—it is essential (Mark 8:34). Just as God raised Christ from the dead, He also brings us to life with Him (Ephesians 2:5).
How Do We Grow?
God created us in His image. He rescues those fallen in Adam and shines the lamp of His truth upon every person. He constantly sows the seed of His Word to produce a hundredfold harvest.
God’s Word is like our breath; without it, we die. It is our food and drink. Jesus taught us to pray for our "daily bread" (Matthew 6:11) to remind us that we must consume His Word daily. To eat and drink His Word is to walk with Him. Apart from Him, we have no life (John 15:4).
God dwells within us forever (John 14:16-17). Following the example of obedience set by the Lord, we fix our eyes on Him and walk the path of faith. We do this knowing that God delights in giving us what we need (John 14:13-14).
"And God is able to bless you abundantly, so that in all things at all times, having all that you need, you will abound in every good work." (2 Corinthians 9:8)
"If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. That person should not expect to receive anything from the Lord. Such a person is double-minded and unstable in all they do." (James 1:5-8)
Amen!
