"Darkness is getting the control where only the Spirit of God should rule. But few who engage in the work realize the necessity of personal effort and individual responsibility in whatever department they occupy. Few feel the sacredness of the work in which they are engaged. They regard it as upon a common level with ordinary enterprises. 4T 186.2"
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Both passages address the presence of darkness or evil influences where God's Spirit should be. Ephesians 6:12 speaks of spiritual warfare against powers of darkness, while the EGW passage speaks of darkness controlling where the Spirit of God should rule. The connection is thematic, relating to spiritual conflict.
"Selfishness predominates with many who should know that a life of self-sacrificing love is a life of peace and liberty. Those who seek happiness by gratifying themselves and looking out mainly for their own interests are on the wrong track to secure happiness even upon earth. Whoever is unfaithful in the least of his duties is unfaithful in greater ones. If he neglects to faithfully perform the small tasks devolving upon him, he proves himself incapable of bearing weightier responsibilities; he indicates that he is not wholehearted in the work and that he does not have an eye single to the glory of God. 4T 186.3"
"His lord said unto him, Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord."
Both passages connect faithfulness in small duties with greater responsibilities and ultimate reward. The EGW passage emphasizes the importance of faithfulness in even the smallest tasks, while Matthew 25:21 rewards the servant who was faithful over a few things. The connection is thematic and meaningful.
"especially in the Health Institute [now sanitarium], and in the office, the church, and the school. If all connected with these institutions were listening eagerly to hear what Jesus directed them to do, instead of turning to ask what this man or that man shall do, we should witness a great change in every department of the work. If the language of each heart was, “I must listen to Christ's teachings, and obey His voice; no one can do my work for me; the attention of others can never repair my negligence,” then we might see the cause of God advancing as it has never yet advanced. 4T 186.4"
"Now ye are the body of Christ, and members in particular."
The EGW passage emphasizes individual responsibility and listening to Christ's teachings, while 1 Corinthians 12:27 speaks of the church as the body of Christ with individual members. While not a direct allusion, the idea of each member fulfilling their role and listening to the head (Christ) creates a possible connection.
