persecutions, afflictions, which happened to me at Antioch, at Iconium, at Lystra - what persecutions I endured. And out of them all the Lord delivered me"
2 Timothy 3:10-11 (NKJV)
When we learn about something, a place, an event, or even a person, there can be a lot of details to learn about it. We might know that Berlin is a city in Germany, but there are a lot more things than that to learn about Berlin. We might know about a man landing on the moon, but do we know when it happened or who was involved? We might know about a person, a personal friend or a public figure, but how much do we really know about them? If we really want to have a good understanding of something, we need to know all the details.
The majority of Christians know who the Apostle Paul is. They might know he was formerly a Pharisee who converted to Christianity and that Paul started churches and wrote many letters. But there are many more things we can learn about the Apostle Paul than just those few facts. There were several people who traveled with Paul and spent time with him, including Timothy, Titus, and Luke. How well did these people know Paul? We can see that Paul lived a life that allowed others to get to know him and how he lived.
In 2 Timothy 3:10-11, Paul said Timothy had carefully followed Paul's doctrine, manner of life, purpose. faith, longsuffering, love, perseverance, persecutions, and afflictions. These were not things that Timothy had only heard about; Timothy knew all the details himself. Paul was not living a secluded life where no one really knew him or what he was doing. Paul worked alongside other people and gave them a living example of a godly life and how to serve God. We too need to give a detailed living example of a godly life that others can learn from.
