But there is no requirement to worship to get the mark. I think some could want to buy and sell and receive the mark but not be fully sold on the worship part.
I think most will worship him but I don't see that it is required for the mark. There are not really religious ppl who are buisiness people who might take the mark just to proper financially but not be into the worship aspect.
That seems impossible, to get the mark of the beast, but not worship the beast. Scriptures sound like you will get the mark if you worship the beast. You would not want the mark of his name if you just wanted to buy and sell, but did not worship the beast. I do not think the two can be separated.
Revelation 14
9 And 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,
10 The 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:
11 And 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.
