Jesus used the contradictory example of light and darkness to convey how God intended his Son coming into the world to affect people. After stating that God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life (John 3:16), Jesus went on to say, “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. But whoever does what is true, comes to the light, so that it may be clearly seen that his works have been carried out in God” (John 3:19-21). Jesus later told his disciples, “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).

Paul explained what it means to have the light of life in his letter to the Philippians. Paul began by using Christ’s example of humility to illustrate what draws people to the light and said that believers are to be of the same mind, “being in full accord and of one mind” (Philippians 2:2). The Greek word sumpsuchos (soomˊ-psoo-khos), which is translated in full accord, is derived from the words sun (soon), “together” (G4862), and psushe (psoo-khayˊ), “soul” (G5590). Sumpsuchos means “of one mind, joined together, at peace or harmony. Found only in Philippians 2:2, where it is used to encourage believers to unity and love. In the context of Philippians 2, sumpsuchos seems to imply a harmony of feeling as well as thought” (G4861). Paul stated that believers are to:

Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others. Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. (Philippians 2:3-8)

Paul said the mind believers are to have among themselves is one of humble obedience. Jesus “humbled himself by becoming obedient to the point of death, even death on a cross” (Philippians 2:8). Paul connected obedience with working out your own salvation, and said, “for it is God who works in you both to will and to work for his good pleasure” (Philippians 2:13). Paul then stated that believers are to “do all things without grumbling or disputing, that you may be blameless and innocent, children of God without blemish in the midst of a crooked and twisted generation, among whom you shine as lights in the world” (Philippians 2:14-15).

The people of Israel were originally God’s lights in the world, but they did not carry out the task God had given them in the way that was expected (Isaiah 43:10-12; 44). Israel became a negative example because of their rejection of God and tendency toward idolatry (Jeremiah 3:6-10). Jonah, the Old Testament prophet who was sent to Niniveh, the capital of the Assyrian Empire, with a message of repentance, chose to flee to Tarshish instead of obeying the command of the LORD (Jonah 1:3). In spite of Jonah’s disobedience, God’s plan was carried out. Jesus referred to Jonah as a sign and said, “The men of Nineveh will rise up at the judgment with this generation and condemn it, for they repented at the preaching of Jonah, and behold, something greater than Jonah is here” (Matthew 12:41).

Jonah thought he could flee from the presence of the LORD (Jonah 1:3), but a hurricane that threatened to break up the ship he was traveling on made Jonah realize that nothing that happened to him was outside of God’s awareness. “Jonah intended to go as far as he could in the opposite direction from the place to which God had sent him. The phrase ‘rose to flee…from the presence of the LORD’ also refers to Jonah’s attempt to escape from the will of God. This does not mean that Jonah thought God could not find him in Tarshish; he may have felt that leaving the place where God had called him, God would no longer desire to have him go to Nineveh. It is often a misconception of God’s people that there are some places where God is more evident than others. They feel that if they go far enough away from these places of God’s ‘presence,’ he will no longer seek to use them” (note on Jonah 1:3). Jonah 1:5-14 states:

Jonah had gone down into the inner part of the ship and had lain down and was fast asleep. So the captain came and said to him, “What do you mean, you sleeper? Arise, call out to your god! Perhaps the god will give a thought to us, that we may not perish.”

And they said to one another, “Come, let us cast lots, that we may know on whose account this evil has come upon us.” So they cast lots, and the lot fell on Jonah. Then they said to him, “Tell us on whose account this evil has come upon us. What is your occupation? And where do you come from? What is your country? And of what people are you?” And he said to them, “I am a Hebrew, and I fear the Lord, the God of heaven, who made the sea and the dry land.” Then the men were exceedingly afraid and said to him, “What is this that you have done!” For the men knew that he was fleeing from the presence of the Lord, because he had told them.

Then they said to him, “What shall we do to you, that the sea may quiet down for us?” For the sea grew more and more tempestuous. He said to them, “Pick me up and hurl me into the sea; then the sea will quiet down for you, for I know it is because of me that this great tempest has come upon you.” Nevertheless, the men rowed hard to get back to dry land, but they could not, for the sea grew more and more tempestuous against them. Therefore they called out to the Lord, “O Lord, let us not perish for this man’s life, and lay not on us innocent blood, for you, O Lord, have done as it pleased you.” (Jonah 1:5-14)

Jonah thought the purpose of the storm was to punish him for not doing what God wanted him to. Jonah instructed the sailors to throw him overboard because he would rather die than carry out the mission that God had given to him. Jonah’s resistance to doing God’s will resulted in the sailors believing in the LORD. The sailors’ prayer demonstrated the sincerity of their belief and their understanding of God’s sovereignty. “O LORD, let us not perish for this man’s life, and lay not on us innocent blood, for you, O LORD, have done as it pleased you” (Jonah 1:14).

Paul said that believers are to work out their own salvation with fear and trembling, “for it is God who works in you both to will and to work for his good pleasure” (Philippians 2:12-13). God’s people are witnesses to him regardless of their desire to do so. God can work in and through believers to accomplish his will even through their disobedience, but what Paul was saying was that it is better for us to work out our own salvation or rather, to willingly offer ourselves up to be used by God no matter how undesirable the task is to us. Jesus asked the question, “’Is a lamp brought in to be put under a basket, or under a bed, and not on a stand? For nothing is hidden except to be made manifest, not is anything secret except to come to light. If anyone has ears to hear, let him hear.’ And he said to them, ‘Pay attention to what you hear: with the measure you use, it will be measured to you, and still more will be added to you. For to the one who has, more will be given, and from the one who has not, even what he has will be taken away’” (Mark 4:21-25).

Paul indicated that the way believers shine as lights in the world is by holding fast to the word of life (Philippians 2:16). The word of life is described in Hebrews 4:12 as being sharper than any two-edged sword, something that is a discerner of the thoughts and intents of the heart. Jonah’s word to the Ninevites was, “Yet forty days, and Nineveh shall be overthrown!” In response to this message, it says in Jonah 3:5, “And the people of Nineveh believed God.” Jonah 3:6-9 goes on to say:

The word reached the king of Nineveh, and he arose from his throne, removed his robe, covered himself with sackcloth, and sat in ashes. And he issued a proclamation and published through Nineveh, “By the decree of the king and his nobles: Let neither man nor beast, herd nor flock, taste anything. Let them not feed or drink water, but let man and beast be covered with sackcloth, and let them call out mightily to God. Let everyone turn from his evil way and from the violence that is in his hands. Who knows? God may turn and relent and turn from his fierce anger, so that we may not perish.”

The people of Nineveh, including the king, took God’s word seriously and repented of their sin with the hope that he might show them mercy. The book of Jonah “was written after Jonah returned from his mission and had time to reflect on its significance. Some have called the book of Jonah the ‘Acts of the Old Testament,’ because it graphically demonstrates that God is willing to have mercy on all who seek him in humility and sincerity. The repentance of the people of Nineveh postponed the destruction of their city for roughly 150 years (until 612 BC)” (Introduction to Jonah).

“Many critics dismiss the story of Jonah as a ‘myth’ or ‘fable’ because they reject the miraculous element of the great fish. This simply shows their inability to comprehend the supernatural nature of the God of the Bible. For one who can stay the sun or divide the Red Sea, controlling one fish is not a great problem. Jesus treated the book as a historical fact, comparing Jonah’s time in the belly of the fish to his own time in the tomb (Matthew 12:40). Moreover, he affirmed that the repentance of the Ninevites was genuine and contrasted their reaction to the indifference of the scribes and Pharisees (Matthew 12:41; Luke 11:32)” (Introduction to Jonah).
