“No one, after lighting a lamp, puts it away in a cellar nor under a basket, but on the lampstand, so that those who enter may see the light.”
In the parable of the Lighted Lamp, the Lamp describes Jesus Christ who is the Light. Like the lamp that is a source of light in darkness, Jesus is the only resource available to those who are given eyes to see. He is the only one able to make a true difference to those who repent and believe in him.
The light of Jesus Christ is supernatural. In heaven, God’s light will illumine the day and the night will go away with all other natural lights no longer needed (Rev. 22:5). Unfortunately, sinners mistakenly think that the lights of this world are enough to find peace. But only the light of Christ is able to bring peace and make the sinner’s heart different.
Whoever has the light of Christ will reflect him in their lives and they shine forth his light to those around them. Christians are lamp stands and do not self-radiate their own light. They reflect Christ’s light.
“The eye is the lamp of your body; when your eye is clear, your whole body also is full of light,”
At the conversion of every believer, they begin to see clearly and their blurry vision as sinners dissipates. When regeneration occurs by the Holy Spirit, conversion follows from being spiritually dead to being made alive to God. Conversion changes the heart and manifests the Christian’s new allegiance to Christ in outward change. Consequently, conversion leads to ongoing transformation as the Christian grows to be more like Christ.
The transformation is a result of the heart change and the heart’s expression is the eye or the body. The inner man is given spiritual eyes that are different from the physical eye of the body. The inner man is given the ability to discern and think of how to glorify God as they are given a new heart. God dwells in the believer. He continues to enlighten the Christian by manifesting himself and his truths through Scripture, which continues to sanctify the inner man.
In the prior life before Christ, the sinner remained in darkness and did not want the light. Their lampstand was void of any light. But having been delivered from darkness and into light, the light is given and will shine forever. In Paul’s conversion, the light of Christ only shone on him and his spiritual eyes were opened even though his physical eyes could no longer see (Acts 9:3-5, 8).
The difference between the unbeliever and the Christian is the believer’s conversion that leads to true transformation. The life of the truly converted must be radically different. It is different from behavioral modification because the heart is changed. Paul changed drastically from when he was Saul to the point where the Jews plotted together to put him to death (Acts 9:23).
The only thing that can make the sinner different is to be given a clear eye that makes the body full of light. The heart change leads to a life that is eternally transformed to be godly and righteous, reflecting the Holy One, the Lord and Savior Jesus Christ.
When the eye is clear, the Christian is given the gift of contentment to live a simple life of devotion to God, his word, fellowship, breaking of bread and prayer (Acts 2:42). In addition, the Christian focuses on the things of the Lord because they become singularly fixed on glorifying Christ through faith. Their lives become more encouraged by the love of Christ and lead a life to loving him alone.
“but when it is bad, your body also is full of darkness.”
The Lord is referring to the wicked generation of unbelievers. But this text can also be applied to some believers who use their freedom to still disobey. Without walking with Christ, the heart can lead to darkness and make sinful decisions that result in consequences even for believers. The self or circumstances must not rule over biblical truth. When this persists, one might need to reassess if their heart has been truly converted because only a life of misery results. Repentance and faith in the Lord Jesus Christ can only provide true light that gives understanding leading to obedience and sanctification.
