Watchman Nee emphasizes the importance of maintaining a continuous testimony for Christ, likening believers to candles that should burn brightly until consumed. He illustrates that each believer's light can ignite others, creating a chain reaction that spreads the Gospel throughout the world. The sermon reflects on how Jesus kindled the first candles, including Paul, and how the Church has carried this light for over 2,000 years. Nee encourages believers to witness for the Lord, ensuring that His testimony shines perpetually. The call to action is clear: to keep kindling new lights even as our own burns out.
