A person, such as yourself, who loves to study the Word of God, would have to be spiritually blind or willfully lawless not to be able to see that the MOTB involves WORSHIP, COMMANDMENT KEEPING, AND SPECIFICALLY THE 4TH COMMANDMENT.
Rev 14:6And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,
7Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and WORSHIP him that made heaven, and earth, and the sea, and the fountains of waters.
(that language comes directly from the 4th commandment)
8And there followed another angel, saying, Babylon is fallen, is fallen, that great city, because she made all nations drink of the wine of the wrath of her fornication.
9And the third angel followed them, saying with a loud voice, If any man WORSHIP the beast and his image, and receive his mark in his forehead, or in his hand,
10The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
11And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who WORSHIP the beast and his image, and whosoever receiveth the mark of his name.
12Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
Rev 14:
7Saying with a loud voice, Fear God, and give glory to him; for the hour of his JUDGMENT is come: and WORSHIP him that made heaven, and earth, and the sea, and the fountains of waters.
12Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
Eccl 12:
13Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man. 14For God shall bring every work into JUDGMENT, with every secret thing, whether it be good, or whether it be evil.
OSAS/OJAJ are in BIG trouble if they think obedience to God's law isn't mandatory after Grace.
