"If we will give ourselves for service to the Lord, He will instruct us what to do. If we will come into close relation with God, He will work with us. Let us not become so absorbed in self and self-interests that we shall forget those who are climbing the ladder of Christian experience and who need our help. We must stand ready to use our God-given capabilities in the work of the Lord, ready to speak words in season and out of season— words that will help and bless. 9T 134.1"
"Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me."
Both passages deal with responding to God's call to service. EGW's passage emphasizes service and helping others, while Isaiah 6:8 is the direct response to God's call. The connection is thematic, but not a direct allusion.
"My brethren and sisters, do we take into consideration the needs of the large cities of the East? Do we not know that they must be warned of Christ's near approach? The work we have to do is a wonderfully great work. There is a world to be saved; there are souls to be labored for in the cities of the East, in the states where the message of the coming of our Lord was first preached. Who will give themselves to do this line of missionary work? There are hundreds of our people who ought to be out in the field who are doing little or nothing for the advancement of the message. Those who have had every advantage of knowing the truth, who have received instruction line upon line, precept upon precept, here a little and there a little, have a great responsibility resting upon them in these souls who have never heard the last gospel message. 9T 134.2"
"And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come."
Both passages discuss the importance of spreading the gospel message to the world. EGW's passage focuses on the need to warn cities of Christ's return, while Matthew 24:14 speaks of the gospel being preached as a sign of the end. The connection is thematic and relevant.
"I must work the works of him that sent me, while it is day: the night cometh, when no man can work."
Both passages emphasize the urgency of doing God's work. EGW's passage speaks of the need to warn cities of Christ's return, while John 9:4 speaks of working while it is day. The connection is thematic, but weaker than other pairs.
"If in this opportune time the members of the churches will come humbly before God, putting out of their hearts all that is wrong and consulting Him at every step, He will manifest Himself to them and will give them courage in Him. And as the church members do their part faithfully, the Lord will lead and guide His chosen ministers, and strengthen them for their important work. In much prayer let us all unite in holding up their hands and in drawing bright beams from the heavenly sanctuary. 9T 134.3"
"Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded."
Both passages emphasize drawing near to God and purifying oneself. EGW's passage speaks of coming humbly before God and consulting Him, while James 4:8 speaks of drawing nigh to God and cleansing oneself. The connection is a direct principle.
"But Moses’ hands were heavy; and they took a stone, and put it under him, and he sat thereon; and Aaron and Hur stayed up his hands, the one on the one side, and the other on the other side; and his hands were steady until the going down of the sun."
The EGW passage speaks of 'holding up their hands' which is a clear reference to the story of Aaron and Hur holding up Moses' hands in Exodus 17:12. The context is similar: supporting leaders in their work.
