Have you ever wondered why Jesus came 2,000 years ago instead of some more recent time in history? Why didn't God wait to send his Son after the invention of the printing press? Imagine how easy it would have been to print his words on a press rather than copying them by hand. Or, why didn't Jesus come some time after the advent of the internet, or after smart phones became common? Imagine if we could take videos of Jesus' sermons on our smartphones, or document his miracles on video and share them on our Facebook pages. Wouldn't that have been more efficient (and convincing to unbelievers) than having Jesus come during a time when there weren't even still images or newspapers to spread the word? In a lot of ways, it seems like Jesus came into the world too early.
But rather than coming too early, the Bible says that Jesus came at just the right time. Galatians 4.4 says, "But when the fullness of time had come, God sent forth his Son, born of woman, born under the law..." What this verse is saying is that God had predetermined a date that Jesus would come into the world to solve the sin problem. No, the date almost certainly was not December 25, 0 B.C., but there indeed was a date that God had determined would be perfect. And when that perfect date arrived ("when the fullness of time had come"), God sent his Son into the world. It was exactly at just the right time, right according to schedule. God didn't make a mistake by sending Jesus 2,000 years before the 21st century. It was the perfect time for him to come.
2,000 years ago, for the first time in history, the known world was unified and enjoyed relative peace under the "Pax Romana," or the peace of Rome. The Roman empire had gone out to virtually every known inhabited nation and had built roads that centralized commerce and communication. For the first time in human history, messengers could travel by road safely, and sea travel had advanced to the point that it was common and relatively safe. As Jesus' disciples would take the message of his life and death across the world, they would use these new roads by land and sea to bring their news. And since Rome ruled the known world, there were no impenetrable borders or places that were off limits to the gospel.
Moreover, since Rome ruled most of the known world, their language also dominated almost every culture. Practically everyone spoke the predominant language of the time: Greek - a language that is more articulate than even modern English. This made it easy for essentially all people of the known world to hear and understand the message of the gospel. No Bible translators were necessary because, in addition to their native languages, almost the whole world knew Greek.
God foresaw this time in human history, and he determined that this was the perfect time into which he would send his Son to solve the sin problem, once and for all.
But from our perspective, the time doesn't seem so right. Forget about the Roman roads and dangerous sea voyages - we have air travel! We can fly to the other side of the word in relative safety with the message of the gospel in less than a day. And for all for he technological and cultural advancements initiated by the Roman empire, the 21st century and all of the technological advancements that we alluded to earlier (smart phones, the internet, television, etc.) would be much more ideal time for the message of Jesus to spread to the whole world. Wouldn't it?
No, not really, for at least three reasons:
1. Technology becomes irrelevant and obsolete over time. We think of the technology of the Roman empire as irrelevant and obsolete because we have made amazing advancements over the past centuries. But at the time, the ancient advancements mentioned earlier were cutting edge. Similarly, the cutting edge technology we have today will be irrelevant and obsolete 100 years from now (if not sooner). If Jesus came today, in 100 years people would be lamenting that he came to early, given the technological advancements that will have been made in the next 100 years. If we judge the appropriate time for Jesus' advent according to humanity's technological advancement, then no matter when Jesus comes, it will have been too early, because technology will always be better at some later date.
2. Additionally, regardless of whatever means there are to propagate the message of the gospel - and no matter how convincing you can make it or how widely you can spread it - people will always find reasons to not believe. For instance, if Jesus were performing miracles on the earth today and those miracles were captured with a smart phone camera, providing video evidence of his divinity, someone would find a reason to doubt that the video was genuine. They'd say the footage was doctored, or that the testimony of the witnesses was unreliable. People will find any number of reasons not to believe the truth. Furthermore, no matter how clear the evidence might be, it is very possible for two distinct people to examine the same evidence and come away with different conclusions.
Jesus came 2,000 years ago and proved his divinity in a variety of ways. And despite the witnesses and the wide reports of his power, people did not believe. They looked the evidence square in the face and refused to believe. The same thing would happen if a video of Jesus' miracles was the most-viewed video on Facebook. Technological advancement does not produce faith. Only God can do that. Moreover, the scriptures testify to the faithfulness of God's word and the accounts therein that testify to the divinity of Jesus and to the veracity of the story of his life, death, and resurrection, yet people refuse to believe it. If they don't believe the Bible, why would they believe a Facebook video?
3. In Luke 16 Jesus tells a story about a rich man who dies and goes to hell. In hell, he asks Abraham, who is in heaven, to resurrect a poor man named Lazarus who had also died, so that Lazarus may go and preach to the rich man's brothers so that they might not suffer a similar fate. The rich man is convinced that if a dead man goes and preaches to them, then his brothers will surely believe such a miraculous sign. But Abraham says that the rich man's brothers already have Moses and the prophets preaching to them from God's word, and if they won't believe Moses and the prophets, then they wouldn't believe even a dead man who came back to life. The same is true of our world today: if people won't believe Moses and the prophets, they also wouldn't believe a miracle caught on camera. Jesus came when he came. His life, death, and resurrection were meticulously recorded and preserved to serve as a testimony to all people who came after him about what he has done. This testimony is enough. It is sufficient.
The bottom line is that God knew the exact right time to send Jesus into the world, and that's when he came. God had been waiting thousands of years for the right time to come, and it came roughly 2,000 years ago. At Christmas we celebrate not only that Jesus came into the world, but also God's perfect timing in sending the Savior.
