This is from the new series (with no translator) on John by Stephen Tong, I marked a specific episode/timestamp down for the topic of: How is evangelical rally been treated (by Reformed), specifically having insertions for witness testimonies, which Tong received backslash for (likely regarding having Michael Liu giving his testimony in between Tong's preaching).
The source is from episode #142, @1:08:30.
Tong's foundational principle is: Without active evangelism, a church is as good as dead.
