"Truth is of God; deception in all its myriad forms is of Satan, and whoever in any way departs from the straight line of truth is betraying himself into the power of the wicked one. Those who have learned of Christ will “have no fellowship with the unfruitful works of darkness.” Ephesians 5:11 . In speech, as in life, they will be simple, straightforward, and true, for they are preparing for the fellowship of those holy ones in whose mouth is found no guile. See Revelation 14:5 . PK 252.3"
"And in their mouth was found no guile: for they are without fault before the throne of God."
EGW directly quotes and references Revelation 14:5, using it to support her point about the importance of truthfulness in speech and life.
"And have no fellowship with the unfruitful works of darkness, but rather reprove them."
Ellen White directly references Ephesians 5:11 in this passage.
"Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it."
Both passages contrast truth and deception, associating truth with God and deception with the devil. EGW's statement amplifies the idea that deception leads to the power of the wicked one, echoing John 8:44's description of the devil as the father of lies.
"Centuries after Naaman returned to his Syrian home, healed in body and converted in spirit, his wonderful faith was referred to and commended by the Saviour as an object lesson for all who claim to serve God. “Many lepers were in Israel in the time of Eliseus the prophet,” the Saviour declared; “and none of them was cleansed, saving Naaman the Syrian.” Luke 4:27 . God passed over the many lepers in Israel because their unbelief closed the door of good to them. A heathen nobleman who had been true to his convictions of right, and who felt his need of help, was in the sight of God more worthy of His blessing than were the afflicted in Israel, who had slighted and despised their God-given privileges. God works for those who appreciate His favors and respond to the light given them from heaven. PK 252.4"
"And many lepers were in Israel in the time of Eliseus the prophet; and none of them was cleansed, saving Naaman the Syrian."
EGW directly quotes Luke 4:27 and uses the story of Naaman as an example.
