The Light of the World

21 For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. 22 Claiming to be wise, they became fools, 23 and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things. – Romans 1:21-23 ESV

17 Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds. 18 They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart. 19 They have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity. 20 But that is not the way you learned Christ! – Ephesians 4:17-21 ESV

Why was a second Adam necessary? Why did Jesus, the Son of God, have to humble Himself by becoming a man and subject Himself to all the temptations and trials that come with living as a human in a fallen world?

The answer to those questions is provided by the apostle Paul.

When Adam sinned, sin entered the world. Adam’s sin brought death, so death spread to everyone, for everyone sinned. – Romans 5:12 ESV

It might be easy to assume that God overreacted to the sin of Adam and Eve. The punishment doesn’t seem to fit the crime. When God discovered what His two image bearers had done, He pronounced curses on both of them, and these curses would be long-term and cross-generational. To Adam God said:

“Because you have listened to the voice of your wife
    and have eaten of the tree
of which I commanded you,
    ‘You shall not eat of it,’
cursed is the ground because of you;
    in pain you shall eat of it all the days of your life;
thorns and thistles it shall bring forth for you;
    and you shall eat the plants of the field.
By the sweat of your face
    you shall eat bread,
till you return to the ground,
    for out of it you were taken;
for you are dust,
    and to dust you shall return.” – Genesis 3:17-19 ESV

Death entered the equation for the very first time. And this death involved much more than the termination of life. It included physical separation from God. One of the immediate aftereffects of the fall was God’s expulsion of Adam and Eve from the garden.

He drove out the man, and at the east of the garden of Eden he placed the cherubim and a flaming sword that turned every way to guard the way to the tree of life. – Genesis 3:24 ESV

Rather than enjoying constant fellowship with God in the beauty of the garden, Adam and his wife found themselves set apart from God. They were denied further access to the garden and prevented from having any further contact with God. Not only that, they lost the right to eat of the tree of life, which appears to have been the source of eternal life. This seems clear from God’s reaction after their transgression.

“Behold, the man has become like one of us in knowing good and evil. Now, lest he reach out his hand and take also of the tree of life and eat, and live forever.” – Genesis 3:22 ESV

God did not want Adam and Eve to continue eating of the tree of life in their current fallen state. Eternal life had been intended for the sole purpose of bringing glory to God and enjoying unbroken fellowship with Him. But sin had changed all that. A holy, righteous God cannot tolerate sin in His presence. As the apostle Paul rhetorically asked: “For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?” (2 Corinthians 6:14 ESV).

One of the immediate results of the sin of Adam and Eve was a change in their awareness. They experienced a significant alteration to their consciousness.

Then the eyes of both were opened, and they knew that they were naked. And they sewed fig leaves together and made themselves loincloths. – Genesis 3:7 ESV

Interestingly enough, this was exactly what Satan had said would happen if they disobeyed God and ate of the forbidden fruit.

“You will not surely die. For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil.” – Genesis 3:4-5 ESV

Their eyes were opened. But they didn’t like what they saw. For the first time, they experienced guilt and shame. They knew they had sinned and were overcome by the condemnation they felt. Their guilty consciences caused them to view themselves differently. They suddenly saw their God-created state in a new and sin-darkened light. The beauty of their bodies became nakedness, and they tried to cover it up. Their eyes were opened, but their vision had become distorted by sin. And this is the very same state into which every man and woman has been born ever since.

As Paul states in the Roman’s passage above, “they became futile in their thinking, and their foolish hearts were darkened.” Opened eyes do not always see clearly. And humanity would find itself blinded by sin and incapable of seeing the truth regarding God and their own fallen state. They would understand their need for God and would spend their lives searching for a means by which they might be restored to their former state of fellowship with Him. 

But unable to find God, they would seek out false gods, exchanging “the glory of the immortal God for images resembling mortal man and birds and animals and creeping things” (Romans 1:23 ESV). In his letter to the Ephesian believers, Paul describes lost mankind in very unflattering terms.

They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them… – Ephesians 4:18 ESV

But he doesn’t stop there. Paul goes on to describe the outcome of their darkened understanding.

They have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity… – Ephesians 4:19 ESV

Created to bear God’s image, but damaged by sin, mankind has spent centuries living in open rebellion to God and failing to reflect His glory. Paul says they “exchanged the glory of the immortal God for images.” Denied access to the one true God, they sought substitutes. As His image bearers, they were to have been the glory of God. But God’s glory in their lives became veiled by sin.

Think of it like the sun darkened by clouds. The glory of God still shines, but sin prevents it from casting God’s shadow on the earth. Which takes us back to what it meant for man to be created in the image of God. The Hebrew word for image is tselem, and according to the Gesenius’ Hebrew-Chaldee Lexicon, it means “an image, likeness (so called from its shadowing forth).” Man was intended to be the shadow of God on earth, created by the glory of His majesty. Like the shadow of a man, created by the brilliance of the sun, humanity was to have revealed the reality of God by its very existence.

Jesus came into the world as the very light of God. The apostle John describes Him this way: “The light shines in the darkness, and the darkness has not overcome it” (John 1:5 ESV). “The true light, which gives light to everyone, was coming into the world. He was in the world, and the world was made through him, yet the world did not know him” (John 1:9-10 ESV).

Why was the second Adam necessary? Because sin had darkened the minds of men. They no longer had the capacity to see truth. Their lives no longer shadowed God’s glory. The darkness of sin had veiled the Light. And John goes on to paint a bleak picture of the world when Jesus arrived on the scene as the second Adam.

And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil. For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed. – John 3:19-20 ESV

Jesus came into the world as the light of God. He shadowed the glory of the light of God perfectly to the world, exposing man’s sin and extending an invitation to step into the light of God’s glory once again. But for man to enjoy fellowship with God again, the guilt and shame of sin must be removed. The darkness veiling the eyes of men must be healed. Blind men can never see the light. Those who have learned to love the darkness of sin will never know what it means to live in the light of God’s glory, without the sin-shattering, darkness illuminating power of the second Adam. It is only through Jesus, the second Adam, that we are able to “put on the new self, created after the likeness of God in true righteousness and holiness” (Ephesians 4:24 ESV). 

Jesus makes it possible for the cloud of sin to be removed so that man can once again reflect the glory of God. Read the following words from the apostle Paul and consider the remarkable gift provided to you by Jesus Christ.

Satan, who is the god of this world, has blinded the minds of those who don’t believe. They are unable to see the glorious light of the Good News. They don’t understand this message about the glory of Christ, who is the exact likeness of God. – 2 Corinthians 4:4 ESV

But God is greater than Satan.

For God, who said, “Let there be light in the darkness,” has made this light shine in our hearts so we could know the glory of God that is seen in the face of Jesus Christ. – 2 Corinthians 4:6 ESV

God sent the light of His Son into the darkness and made it possible for sinful men to be restored to their original purpose: to reflect the glory of God.

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 ESV

The light has shown in the darkness. Jesus, the Son of God and the second Adam, has come into the world so that the darkness of sin might be replaced with the light of God’s glory. He has made it possible for man to be restored to his former position as God’s image bearer.

“I am the light of the world. If you follow me, you won’t have to walk in darkness, because you will have the light that leads to life.”  – John 8:12 ESV
