"Unity Those who speak to the people through our periodicals should preserve unity among themselves. Nothing that savors of dissension should be found in our publications. Satan is always seeking to cause dissension, for well he knows that by this means he can most effectually counteract the work of God. We should not give place to his devices. Christ's prayer for His disciples was: “That they all may be one; as Thou, Father, art in Me, and I in Thee, that they also may be one in Us: that the world may believe that Thou hast sent Me.” John 17:21 . All true laborers for God will work in harmony with this prayer. In their efforts to advance the work all will manifest that oneness of sentiment and practice which reveals that they are God's witnesses, that they love one another. To a world that is broken up by discord and strife, their love and unity will testify to their connection with heaven. It is the convincing evidence of the divine character of their mission. 7T 156"
"That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me."
EGW directly quotes John 17:21, making this an explicit allusion. The context of the EGW passage also directly relates to the theme of unity found in John 17.
"Let the writers for our periodicals dwell as little as possible upon the objections or arguments of opponents. In all our work we are to meet falsehood with truth. Put truth against all personal hints, references, or insults. Deal only in the currency of heaven. Make use only of that which bears God's image and superscription. Press in truth, new and convincing, to undermine and cut away error. 7T 156.1"
"Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;"
Both passages deal with overcoming false arguments and ideas with truth. EGW's passage speaks of using 'truth' to 'undermine and cut away error,' while 2 Corinthians 10:5 speaks of 'casting down imaginations...against the knowledge of God.' The connection is thematic, focusing on the power of truth against falsehood.
"sharp words. It was His gentleness, His unselfish, unassuming spirit, that made Him a conqueror of hearts. The secret of our success lies in revealing the same spirit. 7T 156.2"
"Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls."
Both passages emphasize the importance of gentleness and humility. EGW highlights Christ's 'gentleness, His unselfish, unassuming spirit,' while Matthew 11:29 describes Jesus as 'meek and lowly in heart.' The connection is strong and thematic.
