14 “You are the light of the world. A city set on a hill cannot be hidden. 15 Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. 16 In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.” – Matthew 5:15-16 ESV
Some of Jesus’ first commands were given during His Sermon on the Mount in the early days of His earthly ministry. In His sermon, Jesus addressed a large crowd of Jews, including His disciples. His message was meant to shock and surprise His Hebrew audience, as He frequently referenced the Mosaic Law and demanded a form of righteousness that excelled that of the scribes and Pharisees (Matthew 5:20). His words were difficult to understand and impossible to apply. His commands to exhibit a superior brand of righteousness were inconceivable to people who already found adherence to the 613 ordinances in the Mosaic Law an unachievable standard to keep.
The Israelites in His audience knew they were the chosen people of God. In fact, they took great pride in their status as His set-apart people. Over the centuries, He had repeatedly pointed out the unique privilege they enjoyed as His covenant people.
“I am the Lord; I have called you in righteousness;
I will take you by the hand and keep you;
I will give you as a covenant for the people,
a light for the nations,
to open the eyes that are blind,
to bring out the prisoners from the dungeon,
from the prison those who sit in darkness.” – Isaiah 42:6-7 ESV
“It is too light a thing that you should be my servant
to raise up the tribes of Jacob
and to bring back the preserved of Israel;
I will make you as a light for the nations,
that my salvation may reach to the end of the earth.” – Isaiah 49:6 ESV
Arise, shine, for your light has come,
and the glory of the Lord has risen upon you.
For behold, darkness shall cover the earth,
and thick darkness the peoples;
but the Lord will arise upon you,
and his glory will be seen upon you.
And nations shall come to your light,
and kings to the brightness of your rising. – Isaiah 60:1-3 ESV
The Jews, God’s chosen people in the Old Testament, were to have been an example to the rest of the nations. They were to act as lights to the blind and to provide freedom to those living in captivity to sin. But they failed. Instead, they chose to live like the nations around them. Rather than influencing the world, they became infected by it. Instead of modeling godliness, they mirrored worldliness.
Those who gathered to listen to Jesus’ words were primarily from the working class. They were peasants, farmers, shepherds, craftsmen, fishermen, homemakers, and widows. They were looked down on by their own religious leaders, who viewed them as irreligious law-breakers whose unrighteous behavior forestalled the Messiah’s coming. Yet, Jesus demanded more from them, not less. He reminded them of their status as God-ordained world influencers. Jesus didn’t say, “You should be the light of the world;” He said “You are!” (Matthew 5:14 ESV). But their radiance had dimmed because of their inability to live up to God’s exacting standards. Rather than demonstrating faith and obedience through their adherence to the Law, they treated God’s sacrificial system as a kind of get-out-of-jail-free card. They knew if they sinned, they could get forgiveness. But to make matters worse, the nation of Israel had a track record of apostasy and spiritual adultery that God found unforgivable.
“Has any nation ever traded its gods for new ones,
even though they are not gods at all?
Yet my people have exchanged their glorious God
for worthless idols!
The heavens are shocked at such a thing
and shrink back in horror and dismay,”
says the Lord. – Jeremiah 2:11-12 NLT
So, when Jesus commanded them to let their lights shine, He knew was dropping a truth bomb on His unsuspecting audience that they would both convict and confuse them. He was demanding that they come out of their period of prolonged darkness and shine as lights in a sin-cloaked world. But He knew His words would be impossible to keep without divine help. They would be no more successful at keeping this command than they had been at obeying the 613 regulations found in the Mosaic Law.
The key to keeping all the commands found in the Sermon on the Mount would be the death and resurrection of Jesus. Only by belief in His substitutionary death on the cross and His miraculous restoration to life would they be able to “shine out for all to see” (Matthew 5:16 NLT). It would be His incarnation, crucifixion, and resurrection that provided the means for the Jews in His audience to become the lights they were meant to be.
The apostle John, who had a front-row seat to the Sermon on the Mount, later wrote, “In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made. In him was life, and the life was the light of men. The light shines in the darkness, and the darkness has not overcome it” (John 1:1-5 ESV).
Jesus was the light and He came to illuminate the darkness that pervaded the hearts of men, including the chosen people of God. But John goes on to say, “He came to his own, and his own people did not receive him” (John 1:12 ESV). Many of those who heard His message that day would refuse to believe His words or accept His offer of salvation through faith in Him alone. They would continue to try to earn God’s favor through rule-keeping and sacrifice. Yet, John points out that the alternative Jesus offered was far more preferable and profitable.
But to all who did receive him, who believed in his name, he gave the right to become children of God. – John 1:12 ESV
The command to be lights shining in the darkness applies to all those who have placed their faith in Christ. Light penetrates and permeates. Light illuminates and eliminates the darkness. Just as physical light has a transformative nature, so does the Light of the world. Jesus said, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life” (John 8:12 ESV).
Those who have placed their faith in Jesus Christ have had the darkness of their lives penetrated by the Light. They have been given the Spirit of God, resident within them, to enlighten and empower them to live in such a way that their lives make a difference. But to have an illuminating impact on the world requires that the Light have its full influence. The apostle John wrote: “The darkness is disappearing, and the true light is already shining” (1 John 2:8 NLT). This is a statement of fact. The Light of Christ shines in the lives of those who call themselves His disciples, and they have the responsibility and capability to illuminate and eliminate the darkness that pervades the world.
As light increases and spreads, darkness diminishes and fades. Yet, it would be easy to look at the world and conclude that the darkness is winning. Evil appears to be increasing. But could the problem be that we, as children of light, have allowed the darkness to overtake the light in our own lives? Are our lamps too feeble? Is our faith too small? Is our light too weak to penetrate the darkness around us?
Paul gives us words of encouragement. “The night has advanced toward dawn; the day is near. So then we must lay aside the works of darkness, and put on the weapons of light” (Romans 13:12 ESV). We must live with the realization that the light wins. The darkness loses. There is a movement of God going on that is transforming the world from darkness to light. We may not be able to see it. We may not feel it. But as soon as Jesus entered the world, the light of God penetrated the darkness and began to spread. We have a responsibility to make the light of Christ our highest priority. To do so, we must refuse to love the darkness more than the light. We must choose to live as children of the light, fanning the flame of faith through regular time in the Word, fellowship with other believers, and a reliance upon the Spirit of God for strength, wisdom, and exposure of any darkness that remains in our lives. The darkness in our lives should be diminishing with each passing day. The light – the righteousness and holiness of God – should be increasing.
Everywhere we go, our lives should provide light in the darkness. Our actions should be proof of the transforming power of God made available through Jesus Christ. When Jesus commissioned Paul to take His offer of salvation to the Gentiles, He said, “I am sending you to open their eyes so that they turn from darkness to light and from the power of Satan to God, so that they may receive forgiveness of sins and a share among those who are sanctified by faith in me. (Acts 26:17-18 ESV).
So, not only is the light in our lives to be increasing, slowly and steadily eliminating the last vestiges of darkness; but it is to be emanating from us into the darkness surrounding us.
For God, who said, “Let light shine out of darkness,” has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ. But we have this treasure in jars of clay, to show that the surpassing power belongs to God and not to us. – 2 Corinthians 4:6-7 ESV
We have the light of God within us, and that light should be increasing in intensity and influence. It should be shining through all the cracks and flaws in our lives, revealing the power of God at work within us. When people look at us, they will still see clay jars; flawed, cracked, and seemingly without value. But they should also see God’s light shining through us and out of us to all those around us.
We now have this light shining in our hearts, but we ourselves are like fragile clay jars containing this great treasure. This makes it clear that our great power is from God, not from ourselves. – 2 Corinthians 4:7 NLT
We are simply receptacles of His glory. We are the conduits of His life-changing, darkness-diminishing light. As the children’s song says, “This little light of mine, I’m gonna let it shine! Let it shine, let it shine, let it shine!” But we must never forget that our ability to illuminate others and eliminate darkness is not self-produced, but a by-product of walking in the light. So, let your light (the Light of Christ) shine.
