"God cannot forbear much longer. Already His judgments are beginning to fall on some places, and soon His signal displeasure will be felt in other places. 9T 96.1"
"For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places."
Both passages speak of judgments and calamities occurring in various places as signs of God's displeasure or the end times. Matthew 24:7 lists specific examples, while EGW speaks more generally, but the underlying theme is the same.
"For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;"
Both passages deal with God's wrath or displeasure being revealed against ungodliness. Romans 1:18 is a general statement of this principle, while the EGW passage suggests that judgments are a manifestation of this wrath.
"There will be a series of events revealing that God is master of the situation. The truth will be proclaimed in clear, unmistakable language. As a people we must prepare the way of the Lord under the overruling guidance of the Holy Spirit. The gospel is to be given in its purity. The stream of living water is to deepen and widen in its course. In all fields, nigh and afar off, men will be called from the plow and from the more common commercial business vocations that largely occupy the mind, and will be educated in connection with men of experience. As they learn to labor effectively they will proclaim the truth with power. Through most wonderful workings of divine providence, mountains of difficulty will be removed and cast into the sea. The message that means so much to the dwellers upon the earth will be heard and understood. Men will know what is truth. Onward and still onward the work will advance until the whole earth shall have been warned, and then shall the end come. 9T 96.2"
"The voice of him that crieth in the wilderness, Prepare ye the way of the Lord, make straight in the desert a highway for our God."
The EGW passage directly references preparing the way of the Lord, which is a clear allusion to Isaiah 40:3. The context in EGW expands on this idea in relation to the proclamation of the gospel.
"He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water."
Both passages use the imagery of 'living water' to represent spiritual life and the spread of the gospel. John 7:38 speaks of rivers of living water flowing from believers, while EGW describes the stream of living water deepening and widening.
