"Nehemiah's efforts to restore the worship of the true God had been crowned with success. As long as the people were true to the oath they had taken, as long as they were obedient to God's word, so long would the Lord fulfill His promise by pouring rich blessings upon them. PK 668.1"
"And it shall come to pass, if thou shalt hearken diligently unto the voice of the Lord thy God, to observe and to do all his commandments which I command thee this day, that the Lord thy God will set thee on high above all nations of the earth: And all these blessings shall come on thee, and overtake thee, if thou shalt hearken unto the voice of the Lord thy God."
The EGW passage directly reflects the principle outlined in Deuteronomy 28:1-2: obedience to God's word leads to blessings. The EGW passage states that as long as the people were obedient, God would fulfill His promise with rich blessings, mirroring the conditional promise in Deuteronomy.
