"We entreat the heralds of the gospel of Christ never to become discouraged in the work, never to consider the most hardened sinner beyond the reach of the grace of God. Such may accept the truth in the love of it and become the salt of the earth. He who turns the hearts of men as the rivers of water are turned can bring the most selfish, sin-hardened soul to surrender to Christ. Is aught too hard for God to do? “My word,” He says, “shall not return unto Me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.” 4T 537.1"
"So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it."
The EGW passage directly quotes Isaiah 55:11, making it an explicit allusion.
"Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men."
The EGW passage uses the phrase 'salt of the earth', which is a direct quote from Matthew 5:13.
"God will not place His benediction upon those who are negligent, selfish, and ease-loving—who will not lift burdens in His cause. The “Well done” will be pronounced upon those only who have done well. Every man is to be rewarded “according as his work shall be.” We want an active ministry—men of prayer who will wrestle with God as did Jacob, saying: “I will not let Thee go, except Thou bless me.” If we obtain the victor's crown we must stretch every nerve and exercise every power. We can never be saved in inactivity. To be an idler in the Lord's vineyard is to relinquish all title to the reward of the righteous. 4T 537.2"
"And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be."
The EGW passage directly quotes and applies Revelation 22:12 in the context of reward according to works.
"His lord said unto him, Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord."
The EGW passage uses the phrase 'Well done', which is a direct quote from Matthew 25:21.
"And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me."
The EGW passage directly quotes and applies Genesis 32:26, using Jacob's wrestling as an example of persistent prayer.
