In this sermon, the speaker recounts a challenge he received from a young Chinese student who questioned the reality of the living God. The student pointed out that believers in a dead God would not be able to walk across fire, as some devotees of a particular God did in their religious ceremony. The speaker reflects on how to respond to this challenge and convey the truth of the living God and the gospel. He also expresses gratitude for the success of their gospel meetings and the conversions they have witnessed. The sermon concludes with a discussion of the Lord's work in Bolivia and the importance of consecrating oneself to the service of the Lord.
