"Chapter 46—Instruction to Workers Slowly but surely the wheel of Providence is turning. We know not how soon our Lord will say: “It is done.” His coming is drawing nigh. Soon our opportunities for work will be forever past. Only a little while longer shall we be permitted to labor. My brethren, will you not strive with earnest effort to establish memorials for God throughout the Southern States? Churches should be raised up; houses of worship should be built; small schools and sanitariums should be established; and the publishing interests should be strengthened. 7T 235"
"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 connect the urgency of completing a task (preaching the gospel/establishing memorials) with the approaching end times. Matthew 24:14 states that the end will come after the gospel is preached to all nations, while the EGW passage emphasizes the limited time left to labor.
"The lines of work to be established in different places in the South will need men and women of wisdom and prayer, men and women who will carry the work forward from stage to stage soundly, intelligently— toiling, praying, working economically, as laborers of God's appointment. The situation calls for personal, untiring, united effort. 7T 235.2"
"For we are labourers together with God: ye are God’s husbandry, ye are God’s building."
The EGW passage directly uses the concept of being a 'laborer' with God, echoing the sentiment in 1 Corinthians 3:9. The context of working together is also present.
"One brick upon another, and the highest wall is made; One flake upon another, and the deepest snow is laid. 7T 235.3"
"For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little:"
Both passages use incremental imagery to convey a point. Isaiah 28:10 uses 'precept upon precept' and 'line upon line' to describe learning, while EGW uses 'one brick upon another' and 'one flake upon another' to illustrate building something substantial. The core idea of gradual accumulation is shared.
