"Those who are under the influence of the Spirit of God will not be fanatical, but calm and steadfast, free from extravagance in thought, word, or deed. Amid the confusion of delusive doctrines, the Spirit of God will be a guide and a shield to those who have not resisted the evidences of truth, silencing every other voice but that which comes from Him who is the truth. GW 289.2"
"But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law."
The EGW passage directly reflects the principle of the fruit of the Spirit being manifested in a calm and steadfast demeanor, contrasting with fanaticism. The connection is strong and goes beyond a mere thematic parallel.
"We are living in the last days, when error of a most deceptive character is accepted and believed, while truth is discarded. The Lord will hold both ministers and people responsible for the light shining upon them. He calls upon us to work diligently in gathering up the jewels of truth, and placing them in the framework of the gospel. In all their divine beauty they are to shine forth in the moral darkness of the world. This cannot be accomplished without the aid of the Holy Spirit, but with this aid we can do all things. When we are endowed with the Spirit, we take hold by faith of infinite power. There is nothing lost of that which comes from God. The Saviour of the world sends His messages to the soul, that the darkness of error may be dispelled. The work of the Spirit is immeasurably great. It is from this source that power and efficiency come to the worker for God. GW 289.3"
"This know also, that in the last days perilous times shall come."
The EGW passage explicitly mentions 'the last days' and the deceptive character of error, directly alluding to the warning in 2 Timothy 3:1 about perilous times in the last days.
"Ye are the light of the world. A city that is set on an hill cannot be hid. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
The EGW passage speaks of 'gathering up the jewels of truth' and letting them 'shine forth in the moral darkness of the world,' which strongly parallels the concept of being the 'light of the world' as described in Matthew 5:14-16. Both passages emphasize the importance of revealing truth and goodness to others.
