"Duties in this direction are binding upon all who profess to be followers of Christ. God's law specifies their duty to their fellow men: “Thou shalt love thy neighbor as thyself.” By a disregard of justice, mercy, and benevolence to their neighbor, some have so hardened the heart that they can go still further, and even rob God without compunctions of conscience. Do such close their eyes and their understanding to the fact that God knows, that He reads their every action and the motive which impelled them to it? His reward is with Him, and His work before Him, to give to every man according as his work shall be. Every good and every wrong act, and its influence upon others, is traced out by the Searcher of hearts, to whom every secret is revealed. And the reward will be according to the motives which prompted the action. 2T 520.1"
"And the second is like unto it, Thou shalt love thy neighbour as thyself."
The EGW passage directly quotes Matthew 22:39 ('Thou shalt love thy neighbor as thyself.') and uses it as a basis for discussing duties to fellow men.
"And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be."
Both passages connect actions with rewards, emphasizing that God will give to each person according to their deeds. The EGW passage expands on this by including the influence of actions on others and the importance of motives.
