"Seclusion The incessant reading and writing of many ministers unfits them for pastoral work. They consume valuable time in abstract study, which should be expended in helping the needy at the right moment. Some ministers have given themselves to the work of writing during a period of decided religious interest, and sometimes these writings have had no special connection with the work in hand. At such times it is the duty of the minister to use his entire strength in pushing forward the present interest. His mind should be clear, and centered upon the one object of saving souls. Should his thoughts be preoccupied with other subjects, many might be lost to the cause who could have been saved by timely instruction. GW 337"
"And this I speak for your own profit; not that I may cast a snare upon you, but for that which is comely, and that ye may attend upon the Lord without distraction."
Both passages discuss the importance of focusing on the Lord's work without distraction. The EGW passage applies this to ministers and their duties, while the verse in 1 Corinthians speaks more generally about attending to the Lord.
"When the temptation comes to seclude themselves, and to indulge in reading and writing at a time when other duties claim their immediate attention, ministers should be strong enough to deny self, and devote themselves to the work that lies directly before them. This is undoubtedly one of the most trying tests that a studious mind is called to undergo. GW 337.2"
"Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me."
The EGW passage directly applies the principle of self-denial from Matthew 16:24 to the specific context of ministers resisting the temptation to seclude themselves for study.
"The duties of a pastor are often shamelessly neglected because the minister lacks strength to sacrifice his personal inclinations for seclusion and study. The pastor should visit from house to house among his flock, teaching, conversing, and praying with each family, and looking out for the welfare of their souls. Those who have manifested a desire to become acquainted with the principles of our faith should not be neglected, but thoroughly instructed in the truth. GW 337.3"
"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,"
Both passages emphasize the importance of teaching and visiting people in their homes. The EGW passage elaborates on the specific duties of a pastor, while Acts 20:20 describes Paul's ministry.
"Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee."
The EGW passage elaborates on the pastoral duties mentioned in 1 Timothy 4:16, emphasizing teaching, visiting, and caring for the flock, which aligns with taking heed to oneself and the doctrine.
