"If, instead of preaching to them, the speaker would try to teach them, speaking in a conversational tone and asking them questions, their minds would be aroused to activity, and they would be able more clearly to comprehend the words spoken. GW 167.1"
"And how I kept back nothing that was profitable unto you, but have shewed you, and have taught you publickly, and from house to house,"
The EGW passage suggests teaching through conversation and questions to engage the audience, which thematically aligns with Acts 20:20, where Paul taught publicly and from house to house, implying a more personal and interactive approach. While not a direct quote, the underlying principle of engaging the audience is present.
"***** Small Congregations —Do not become discouraged when there are only a few present to listen to a discourse. Even if you have but two or three hearers, who knows whether there may not be one with whom the Spirit of the Lord is striving? The Lord may give you a message for that one soul, and he, if converted, may be the means of reaching others. All unknown to you, the results of your labor may be multiplied a thousand-fold. GW 167.2"
"For where two or three are gathered together in my name, there am I in the midst of them."
The EGW passage directly echoes the sentiment and context of Matthew 18:20, focusing on the presence of God even in small gatherings and the potential impact of reaching even a few individuals.
"Do not look at the empty seats, and let your faith and courage sink; but think of what God is doing to bring His truth before the world. Remember that you are co-operating with divine agencies—agencies that never fail. Speak with as much earnestness, faith, and interest as if there were thousands present to listen to your voice. GW 167.3"
"For we are labourers together with God: ye are God’s husbandry, ye are God’s building."
Both passages emphasize the idea of working in conjunction with God. EGW speaks of cooperating with divine agencies, while 1 Corinthians 3:9 explicitly states that believers are laborers together with God.
