"Reverence should be shown for God's representatives—for ministers, teachers, and parents, who are called to speak and act in His stead. In the respect shown them, God is honored. PK 237.1"
"Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you."
Both passages emphasize respect and obedience towards those in positions of spiritual authority. EGW expands the application to ministers, teachers, and parents, while Hebrews focuses on those who 'have the rule over you,' but the underlying principle is the same.
"Courtesy, also, is one of the graces of the Spirit and should be cultivated by all. It has power to soften natures which without it would grow hard and rough. Those who profess to be followers of Christ, and are at the same time rough, unkind, and uncourteous, have not learned of Jesus. Their sincerity may not be doubted, their uprightness may not be questioned; but sincerity and uprightness will not atone for a lack of kindness and courtesy. PK 237.2"
"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."
EGW's statement that those who are unkind and uncourteous have not learned of Jesus directly reflects the principle in Matthew 11:29, where Jesus describes himself as meek and lowly in heart and invites others to learn from him. The connection is a direct application of Jesus' teaching.
"But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,"
EGW's discussion of courtesy as a grace of the Spirit aligns with Galatians 5:22, which lists the fruits of the Spirit, including gentleness and goodness. The connection is thematic, as EGW elaborates on specific aspects of the Spirit's fruit.
"The kindly spirit that enabled Elisha to exert a powerful influence over the lives of many in Israel, is revealed in the story of his friendly relations with a family dwelling at Shunem. In his journeyings to and fro throughout the kingdom “it fell on a day, that Elisha passed to Shunem, where was a great woman; and she constrained him to eat bread. And so it was, that as oft as he passed by, he turned in thither to eat bread.” The mistress of the house perceived that Elisha was “an holy man of God,” and she said to her husband: “Let us make a little chamber, I pray thee, on the wall; and let us set for him there a bed, and a table, and a stool, and a candlestick: and it shall be, when he cometh to us, that he shall turn in thither.” To this retreat Elisha often came, thankful for its quiet peace. Nor was God unmindful of the woman's kindness. Her home had been childless; and now the Lord rewarded her hospitality by the gift of a son. PK 237.3"
"And it fell on a day, that Elisha passed to Shunem, where was a great woman; and she constrained him to eat bread. And so it was, that as oft as he passed by, he turned in thither to eat bread."
EGW directly quotes 2 Kings 4:8.
"Be not forgetful to entertain strangers: for thereby some have entertained angels unawares."
Both passages deal with hospitality and receiving blessings as a result. The Shunammite woman's hospitality is rewarded, echoing the sentiment in Hebrews 13:2 about entertaining strangers.
