Behold, I set before you this day a blessing and a curse;
A blessing, if ye obey the commandments of the Lord your God, which I command you this day:
And a curse, if ye will not obey the commandments of the Lord your God, but turn aside out of the way which I command you this day, to go after other gods, which ye have not known.
And it shall come to pass, when the Lord thy God hath brought thee in unto the land whither thou goest to possess it, that thou shalt put the blessing upon mount Gerizim, and the curse upon mount Ebal. -Dake A.R.Bible.
All blessings and curses of Scripture are based upon obedience and disobedience to the will of God as revealed therein.
If all free moral agents had obeyed God from their creation until now, there would have been no sin, and no curse of any kind in the entire universe.
All God’s covenants are based upon this principle of right and wrong, sin and righteousness. There is no such thing in Scripture as the government of God or man without strict obedience to law as the basis of assurance of continued grace or favor with those in charge of the government.
In the event of sins against both God and man there must be punishment to assure continued respect for government and those who govern.
It would be a great incentive to rebels if they knew there would be no punishment for rebellion. No government could long endure where there was leniency or respect of persons with those who plot and practice the overthrow of good government.
If laws and penalties are revealed to subjects of government and they ignore, reject, and wilfully disobey them; if the government is loose and the rulers too weak to punish rebellion; or, if, rulers are too lenient, merciful and forbearing to execute the laws and mete out judgment to sustain good government, rebels will take over.
God is not such a ruler, nor does He carry on a weak government. He upholds law and order and metes out punishment and reward as required, thus qualifying Himself as being capable of His sovereignty and moral responsibility.
Whether the subjects are holy angels or men, God must demand obedience to all His laws and He is under obligation to punish as His Law prescribes or bless as He has promised whenever disobedience or obedience is rendered.
For God to be lenient in just one case and fail to execute punishment upon the sinner would break down respect for Him in the hearts of all others who are assured of Justice should they sin.
There can be no respect of persons with Him [Romans 2:11; Jas. 2:9-10]
Mount Gerizim, located south, and mount Ebal north of Shechem [v29; 27:12; Josh. 8:33-34] extend east to west almost parallel with the beautiful valley of Shechem.
They are about 2 700 to 2 800 ft. high, about 6oo ft. apart, 3 miles long and somewhat in a semi-circle.
Mount Ebal is more barren; Gerizim to the south is more beautiful and fertile, so that the two mountains by nature could be emblems of blessing and cursing.
