"A signpost was erected by God for those journeying through this world. One arm of this signpost pointed out willing obedience to the Creator as the road to felicity and life, while the other arm indicated disobedience as the path to misery and death. The way to happiness was as clearly defined as was the way to the city of refuge under the Jewish dispensation. But in an evil hour for our race, the great enemy of all good turned the signpost around, and multitudes have mistaken the way. PK 179.2"
"I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live:"
Both passages present a choice between two paths with different consequences, life/death, blessing/cursing vs. felicity/misery. EGW's signpost analogy is a clear parallel to Deuteronomy's presentation of choices.
"Thus saith the Lord, Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest for your souls. But they said, We will not walk therein."
Both passages speak of a correct path and people refusing to follow it. EGW's signpost being turned around is analogous to people refusing to walk in the 'old paths' and 'good way' in Jeremiah.
"Through Moses the Lord instructed the Israelites: “Verily My Sabbaths ye shall keep: for it is a sign between Me and you throughout your generations; that ye may know that I am the Lord that doth sanctify you. Ye shall keep the Sabbath therefore; for it is holy unto you: everyone that defileth it shall surely be put to death: for whosoever doeth any work ... in the Sabbath day, he shall surely be put to death. Wherefore the children of Israel shall keep the Sabbath, to observe the Sabbath throughout their generations, for a perpetual covenant. It is a sign between Me and the children of Israel forever: for in six days the Lord made heaven and earth, and on the seventh day He rested, and was refreshed.” Exodus 31:13-17 . PK 179.3"
"Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep: for it is a sign between me and you throughout your generations; that ye may know that I am the Lord that doth sanctify you. Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth any work therein, that soul shall be cut off from among his people. Six days may work be done; but in the seventh is the sabbath of rest, holy to the Lord: whosoever doeth any work in the sabbath day, he shall surely be put to death. Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. It is a sign between me and the children of Israel for ever: for in six days the Lord made heaven and earth, and on the seventh day he rested, and was refreshed."
Ellen White directly references Exodus 31:13-17 in this passage.
"In these words the Lord clearly defined obedience as the way to the City of God; but the man of sin has changed the signpost, making it point in the wrong direction. He has set up a false sabbath and has caused men and women to think that by resting on it they were obeying the command of the Creator. PK 179.4"
"But in vain they do worship me, teaching for doctrines the commandments of men."
EGW's statement about a 'false sabbath' and people thinking they are obeying God while following human commandments directly echoes the sentiment in Matthew 15:9, where worship is in vain because it is based on the commandments of men rather than God's commands.
"Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God."
EGW's reference to the 'man of sin' changing the signpost and setting up a false sabbath aligns with the description of the antichrist figure in 2 Thessalonians 2:4 who exalts himself above God.
