⁴⁴ And Jesus cried out and said, “Whoever believes in me, believes not in me but in him who sent me. ⁴⁵ And whoever sees me sees him who sent me. ⁴⁶ I have come into the world as light, so that whoever believes in me may not remain in darkness. ⁴⁷ If anyone hears my words and does not keep them, I do not judge him; for I did not come to judge the world but to save the world. ⁴⁸ The one who rejects me and does not receive my words has a judge; the word that I have spoken will judge him on the last day. ⁴⁹ For I have not spoken on my own authority, but the Father who sent me has himself given me a commandment—what to say and what to speak. ⁵⁰ And I know that his commandment is eternal life. What I say, therefore, I say as the Father has told me.” – John 12:44-50 ESV

In this passage, John describes Jesus as crying out. He literally shouted, as if to ensure that everyone within the sound of His voice would not only hear what He had to say but understand its importance. The reason for raising His voice seems clear. Jesus is explaining the dramatic consequences that come with belief in Him. Earlier, in His late-night encounter with Nicodemus, Jesus had explained some of the other outcomes of expressing belief in Him.

“…whoever believes in him may have eternal life.” – John 3:15 ESV

“…whoever believes in him [God’s Son] should not perish but have eternal life.” – John 3:16 ESV

“Whoever believes in him is not condemned…” – John 3:18 ESV

Later in his gospel, John records the words of Jesus spoken to the crowd who had experienced the miracle of the feeding of the 5,000.

“I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst.” – John 6:35 ESV

“Truly, truly, I say to you, whoever believes has eternal life.” – John 6:47 ESV

And sometime later, on the final day of the Feast of Booths, Jesus declared another benefit or consequence of believing in Him.

“Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.’” – John 7:38 ESV

On another occasion, after having arrived in Bethany and hearing the news that His friend Lazarus had died, Jesus informed Martha:

“Whoever believes in me, though he die, yet shall he live, and everyone who lives and believes in me shall never die.” – John 11:25-26 ESV

Belief in Jesus comes with some fairly significant benefits: Eternal life, freedom from judgment, release from death’s grip, and complete spiritual satisfaction and sustenance.

But now, with His voice raised for added emphasis, Jesus announces another vital consequence that accompanies belief in Him: Access to God.

“If you trust me, you are trusting not only me, but also God who sent me. For when you see me, you are seeing the one who sent me.” – John 12:44-45 NLT

With this emphatic statement, Jesus stresses His unity with the Father. He wants His audience to know that to believe in Him is really an expression of belief in God because He had been sent by God. And, by inference, a failure to believe in Jesus would be nothing less than a refusal to believe in the one who sent Him. Jesus was not operating on His own initiative. He was on a divine mission, sanctioned by God Himself.

It’s important to note that John placed this statement from Jesus immediately after his notation about those who believed.

Many people did believe in him, however, including some of the Jewish leaders. But they wouldn’t admit it for fear that the Pharisees would expel them from the synagogue. For they loved human praise more than the praise of God. – John 12:42-43 NLT

Their belief was mixed with timidity and fear – primarily a fear of man. But, as John’s careful ordering of events suggests, there was much more going on than meets the eye. These people had failed to understand the vital link between Jesus and His Heavenly Father. While they believed Jesus to be someone of great significance, possibly even the Messiah, they were less convinced of the indisputable reality of Jesus’ deity and unrivaled unity with God. To believe in Him was to believe in God. To see Him was to see God. Jesus was boldly declaring His identity as the Son of God.

Just days later, Jesus would respond to a request from Phillip, one of His own disciples.

“Lord, show us the Father, and it is enough for us.” Jesus said to him, “Have I been with you so long, and you still do not know me, Philip? Whoever has seen me has seen the Father. How can you say, ‘Show us the Father’? Do you not believe that I am in the Father and the Father is in me? The words that I say to you I do not speak on my own authority, but the Father who dwells in me does his works. Believe me that I am in the Father and the Father is in me, or else believe on account of the works themselves.” – John 14:8-11 NLT

This link between God the Son and God the Father was to be a vital element of their belief. Believing Jesus to be a supernaturally gifted man who had been sent by God was not enough. Even believing that Jesus was the long-awaited Messiah promised by God was insufficient. Jesus was differentiating Himself from everyone else. He was not merely a well-spoken Rabbi. He was much more than a miracle-working teacher from Nazareth. And, even in His role as Messiah, He was far more than they could have ever imagined. He was the Son of God and the light of the world.

“I have come as a light to shine in this dark world, so that all who put their trust in me will no longer remain in the dark.” – John 12:46 NLT

What these people needed to understand was that they were living in spiritual darkness, completely separated from God because of their sin. Their attempts to satisfy God through law-keeping had been completely unsuccessful and could do nothing to mitigate their state of condemnation and spiritual separation from God.

So it is clear that no one can be made right with God by trying to keep the law. For the Scriptures say, “It is through faith that a righteous person has life.” – Galatians 3:11 NLT

For no one can ever be made right with God by doing what the law commands. The law simply shows us how sinful we are. – Romans 3:20 NLT

Jesus was simply reiterating what John stated in the opening verses of his gospel.

The Word gave life to everything that was created,
    and his life brought light to everyone.
The light shines in the darkness,
    and the darkness can never extinguish it. – John 1:4-5 NLT

In the natural realm, darkness is an absence of light. But the same thing is true of the spiritual realm. To live in darkness is to live apart from the light of God. It is to experience an absence of His presence, provision, and power. Much later in life, John would discuss this important reality in a letter he wrote to believers living in the late-1st-Century.

This is the message we heard from Jesus and now declare to you: God is light, and there is no darkness in him at all. So we are lying if we say we have fellowship with God but go on living in spiritual darkness; we are not practicing the truth. But if we are living in the light, as God is in the light, then we have fellowship with each other, and the blood of Jesus, his Son, cleanses us from all sin. – 1 John 1: 5-7 NLT

And Jesus was saying it was impossible to have fellowship with the Father without understanding that He was the Father’s Son. He was the very light of God illuminating the darkness of men’s lives and revealing the glory of the Father. Through belief in Him, sinful men and women could experience the joy of walking in the light of God’s glorious presence.

As the light of God, Jesus did not come to expose the sins of men, but to cleanse and forgive them. As He has stated before, His mission was not to judge the world but to provide salvation. But there would be dire consequences for those who refused to walk in the light. They would remain in spiritual darkness, condemned by their sin, and facing a future day of judgment that would result in eternal separation from God the Father.

“I will not judge those who hear me but don’t obey me, for I have come to save the world and not to judge it. But all who reject me and my message will be judged on the day of judgment by the truth I have spoken.” – John 12:47-48 NLT

Again, Jesus is simply expanding on the message He delivered to Nicodemus.

“…anyone who does not believe in him has already been judged for not believing in God’s one and only Son. And the judgment is based on this fact: God’s light came into the world, but people loved the darkness more than the light, for their actions were evil. All who do evil hate the light and refuse to go near it for fear their sins will be exposed. But those who do what is right come to the light so others can see that they are doing what God wants.” – John 3:18-21 NLT

Notice what Jesus said. Those who refuse to believe in Him are really refusing to believe in “God’s one and only Son.” They are rejecting the Son of God. They are turning their backs on the light of God and, in so doing, they are expressing their love for the darkness. And Jesus closes out His short but vital discourse with a reminder that His words were not His own. He was acting as the mouthpiece for God. All that He has said was directly from the lips from His Father in heaven.

“I don’t speak on my own authority. The Father who sent me has commanded me what to say and how to say it. And I know his commands lead to eternal life; so I say whatever the Father tells me to say.” – John 12:49-50 NLT

So, in other words, it would pay to listen to what He had to say. These were not the words of a mere man. They were the very words of God Almighty and they came from the lips of His one and only Son.
