You are correct, and to add more to it:
Revelation 13:15-18
And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed.
16And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
The verse here says all! That's every living man woman and child on the earth! Sin is the transgression of the law and all have sinned.
17And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
I have stated it before, and I will state it again. If you are waiting on some form of microchip to decide on whether you can buy or sell anything you are in grave error! Buying and selling is about the TRUE Gospel message! Now let's look at verse 17.
Exodus 13:6-9
Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to the LORD.
7Unleavened bread shall be eaten seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee in all thy quarters.
8And thou shalt shew thy son in that day, saying, This is done because of that which the LORD did unto me when I came forth out of Egypt. 9And it shall be for a sign unto thee upon thine hand, and for a memorial between thine eyes, that the LORD's law may be in thy mouth: for with a strong hand hath the LORD brought thee out of Egypt.
The Bible is meant to be read with a spiritual eye. A day is as a thousand years with the Lord so for seven thousand years we are to obey the Lord only! We are NOT to mix the truth of God with any pagan worship! On the seventh day is a feast of the Lord (Jesus returning to earth).
The name of the Beast. How many names do we have for God? Jehovah, YHWH, Yahweh, and Allah just to name a few. Although there are many names, how do we know spiritually that it is the Most High God we are calling on?
Exodus 32:13
13Speak 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.
The Sabbath is a sign to be kept forever! It is the sign of indentification. It identifies the one true God with his people. Again, using the spiritual eye we know that a day with the Lord is as 1000 years.... But this DOESN'T apply here! In Genesis, we have God creating in six days and resting IN the seventh. Then we notice that with the forming of Adam it was the Lord God! We must be circumcised on the eighth day as we are STILL in God's spiritual seventh day!
The number of His name. Are there three in one, two in one, or one with three manifestations?
Deuteronomy 6:1-8
1Now these are the commandments, the statutes, and the judgments, which the LORD your God commanded to teach you, that ye might do them in the land whither ye go to possess it:
2That thou mightest fear the LORD thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son's son, all the days of thy life; and that thy days may be prolonged.
3Hear therefore, O Israel, and observe to do it; that it may be well with thee, and that ye may increase mightily, as the LORD God of thy fathers hath promised thee, in the land that floweth with milk and honey.
4Hear, O Israel: The LORD our God is one LORD:
5And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.
6And these words, which I command thee this day, shall be in thine heart:
7And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up. 8And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes.
Who is Israel's God? The same God that Jesus had! Even in Revelation, Jesus had a God!
18Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.
God made man in His image and since then, man has been trying to make God in theirs! It reminds me of the movie "Groundhog day." Man will not come out of the sixth day into the rest of the seventh!
