"The work should not stop when the meetings on the camp ground close. Doctrines have been presented that are new and strange to the people. Those who are convicted and who desire to accept the truth, will have to meet the most determined and subtle opposition. Ministers, friends, and acquaintances will put forth every effort to catch away the seeds of truth sown in the heart. We must not leave the seed to be thus caught away. We must not allow it to wither for want of moisture. 6T 74.1"
"When any one heareth the word of the kingdom, and understandeth it not, then cometh the wicked one, and catcheth away that which was sown in his heart. This is he which received seed by the way side."
The EGW passage directly alludes to the parable of the sower in Matthew 13:19, specifically mentioning the danger of the 'wicked one' catching away the seeds of truth sown in the heart. The language and imagery are very similar, indicating a clear connection.
"Changes tend to weaken the influence of the meetings. Continue the meetings on the camp ground whenever practicable. But when it seems advisable to move, let the large tent be removed to some favorable location, and let the services in it be continued. A mission should be established. Secure a suitable place, and let a number of workers unite to form a mission family. This should be in charge of a man and his wife who are persons of ability and consecration and whose influence will give character to the work. 6T 74.2"
"And a certain woman named Lydia, a seller of purple, of the city of Thyatira, which worshipped God, heard us: whose heart the Lord opened, that she attended unto the things which were spoken of Paul. And when she was baptized, and her household, she besought us, saying, If ye have judged me to be faithful to the Lord, come into my house, and abide there. And she constrained us."
Both passages involve establishing a base of operations (Lydia's house/mission family) to further the work after an initial evangelistic effort. The connection is thematic, not a direct quote or principle, but it's present.
"In following up the interest after a camp meeting, helpers are needed in various lines, and these occasions should be as a training school for workers. Let young men work in connection with experienced laborers who will pray with them and patiently instruct them. Consecrated women should engage in Bible work from house to house. Some of the workers should act as colporteurs, selling our literature and giving judiciously to those who cannot buy. 6T 74.3"
"And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also."
EGW's statement about training young workers alongside experienced ones to teach others directly echoes the principle in 2 Timothy 2:2. The connection is strong and intentional.
"Let some of the workers attend religious gatherings in other churches and, as there is opportunity, take part in them. Jesus when only twelve years old went into the school of the priests and rabbis at the temple and asked questions. In this temple school, studies were conducted daily, somewhat as we conduct Bible studies. Jesus asked questions as a learner, but His questions furnished new matter for those learned priests to think upon. Similar work might be done today. Judicious young men should be encouraged to attend the meetings of the Young Men's Christian Association, not for the sake of contention, but to search the Scriptures with them and suggest helpful questions. 6T 74.4"
"And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions. And all that heard him were astonished at his understanding and answers."
EGW explicitly references the story of Jesus in the temple (Luke 2:46-47) and draws a parallel to modern-day religious gatherings. This is a clear and direct allusion.
