Claim. Arriving for the whole service trains the church and its children that gathered worship is worth full attention.
Elaboration. The speakers reject treating the opening songs as expendable. One exhortation asks why believers would not bring the “full hour and 15 minutes” of attention and affection to God, especially when people arrive early for costly concerts but late for worshiping “the God of the universe” (20:17-21:37, Transcript). The follow-up names the formation effect: missing the call to worship every week trains people that the beginning is unimportant, and it withholds encouragement from the congregation “from the get-go” (21:37-22:13).
Implication. This is a practical form of sunday-service-as-harvest: presence is part of what the community brings, not just the room one enters late.
