If You Don't Keep the Sabbath, Then Who do You Worship?

The book of Revelation clearly shows that the issue of the last days has to do with worship.

And 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, Saying 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. And 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. 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, 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: 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. Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus. And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
- Revelation 14:6-13 (KJV)

So there are two choices:

  • Worship God
  • Worship satan

How can we tell them apart?

And hallow my sabbaths; and they shall be a sign between me and you, that ye may know that I am the Lord your God.
- Ezekiel 20:20 (KJV)

So, if you keep the Sabbath that is a clear sign between God and you.

Keeping the Sunday is the mark of the beast (satan).

Of course the Catholic Church claims that the change [from Sabbath to Sunday] was her act. And the act is the mark of her ecclesiastical power and authority in religious matters.
- Faith of Our Fathers, p. 14 C.F. Thomas, Chancellor of Cardinal Gibbons

The Roman Catholic Church considers herself above God's Law, and has changed the Sabbath to Sunday (satan's sign if you will).

If you do not keep the Sabbath then who are you worshiping exactly?

Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
- Mark 7:7 (KJV)

You are worshiping another "god", and you have broken the first commandment.

Thou shalt have no other gods before me.
- Exodus 20:3 (KJV)

Summary

You will either live with God in obedience, or die with satan in rebellion.

God wants to know who you worship, e.g. whose Law do you keep?

If ye love me, keep my commandments.
- John 14:15 (KJV)

It's that "simple".
