Philippians 1:5 “For your fellowship in the gospel from the first day until now”.
Of course the “gospel” means good news, and what better news than that Jesus saves. And these people were interested in sharing it and in it. “For your fellowship in the gospel” they saw this as a serving ministry. They had been shown the need and now wanted to help others see as well. And they didn’t wait to get started, “from the first day” and didn’t stop either, “until now”.
– Also we see here that Paul had three specific days in mind:
1. the first day- that being the day they were saved. v5
2. until now- the present day they were reading this. v5
3. day of Jesus- time of rapture. v6
