"The Lord has shown me that men in responsible positions are standing directly in the way of His work because they think the work must be done and the blessing must come in a certain way, and they will not recognize that which comes in any other way. My brethren, may the Lord place this matter before you as it is. God does not work as men plan, or as they wish; He “moves in a mysterious way His wonders to perform.” Why reject the Lord's methods of working, because they do not coincide with our ideas? God has His appointed channels of light, but these are not necessarily the minds of any particular set of men. When all shall take their appointed place in God's work, earnestly seeking wisdom and guidance from Him, then a great advance will have been made toward letting light shine upon the world. When men shall cease to place themselves in the way, God will work among us as never before. 5T 726.1"
"For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts."
The EGW passage directly alludes to the idea that God's ways are not our ways, which is the central theme of Isaiah 55:8-9.
"While extensive plans should be laid, great care must be taken that the work in each branch of the cause be harmoniously united with that in every other branch, thus making a perfect whole. But too often it has been the reverse of this; and, as the result, the work has been defective. One man who has the oversight of a certain branch of the work magnifies his responsibilities until, in his estimation, that one department is above every other. When this narrow view is taken, a strong influence is exerted to lead others to see the matter in the same light. This is human nature, but it is not the spirit of Christ. Just in proportion as this policy is followed, Christ is crowded out of the work, and self appears prominent. 5T 726.2"
"For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ."
Both passages discuss the importance of unity and harmony within a larger body, with 1 Corinthians 12:12 using the analogy of the human body and its members.
