The true God

The true God is the creator of the heavens and the Earth.
Genesis 1:1 In the beginning God created the heavens and the Earth. Genesis 1:31 And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day. Genesis 2:1 Thus the heavens and the earth were finished, and all the host of them.

Genesis 2:2-3 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made. God makes it clear to us that the 7th day is different from all other days. It is a special day. Why? Because Sabbath keeping is the sign that identifies us as worshippers of the true God.

Exodus 31:13 "But as for you, speak to the sons of Israel, saying, 'You shall surely observe My sabbaths; for this is a sign between Me and you throughout your generations, that you may know that I am the LORD who sanctifies you.

If you keep Sunday or any day other than the 7th day or Sabbath, not only are you disobeying God, you are worshipping another God, not the creator.

The reason behind this deception is the Devil. Satan does not want you to know and worship the true God; Satan wants you to disobey the true God. Genesis 3:1 Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden? Satan deceived Eve into disobeying God. Those who worship SUNday worship the SUN, we worship the SON.

Luke 4:16 And He came to Nazareth, where He had been brought up; and as was His custom, He entered the synagogue on the Sabbath, and stood up to read.For how long will the Sabbath be a sign?

Isaiah 66:22
"For just as the new heavens and the new earth
Which I make will endure before Me," declares the LORD,
"So your offspring and your name will endure.
Isaiah 66:23
"And it shall be from new moon to new moon
And from sabbath to sabbath,
All mankind will come to bow down before Me," says the LORD.

When God takes us to the new earth, we will still have to keep the Sabbath.
These are the signs that you are a true follower:
1: If you believe that God created the world and everything in it in 6 days and rested on the 7th and sanctified the 7th and you keep it as God kept it and sanctified it.

2: If you believe Jesus is the Messiah and you believe in the only sign He said He would give which is that He would stay in the belly of the earth for 3 days and 3 nights.
