Jesus say in (Mat.7:21) “Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven”. For students to succeed in school, students learn to follow their teachers' instructions, and learn their lessons carefully. But few apply this method when they are dealing with the word of God. Is Jesus your Lord? Then why don’t you do the things he says. (Luke 6:46) “And why call ye me, Lord, Lord, and do not the things which I say”? He told you plainly: (Ex 20:8-10) (v.8) Remember the Sabbath day, to keep it holy. (v.9) Six days shalt thou labour, and do all thy work: (v.10) “But the seventh day is the Sabbath of the LORD thy God”.
Paul say in 2 Corinthians 11:4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him. Now any Christian in their right mind wouldn’t dare say that it’s okay to steal, kill or commit adultery or break any of the other seven commandments. But when it comes to the fourth commandment, people avoid it like a plague! They are either uninformed about which day is the Sabbath day of the God of the Bible or they are just following the tradition of religion that was passed down through the family or maybe they have let some preacher give them other excuses for ignoring God’s true day of worship.
The Sabbath Day of the Lord -God of the Bible. (Gen.2:2-5) (v.2) 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. (v.3) And God blessed the seventh day (every seventh day of the week is a blessed and holy day) and sanctified it (it is a day that is separated (sanctified) for a purpose) because that in it he had rested from all his work which God created and made. (v.5) “and there was not a man to till the ground.” There was not a Jew, Catholic, Baptist, or Seventh Day Adventist; in fact, there was not a Christian when He constituted the Sabbath Day!
Remember that it was Christ: (1Peter:2: 22) Who did no sin, neither was guile found in his mouth: Jesus did no sin. But what is sin? (1John:3:4) Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law. So every time you break (transgress) one of God’s commandments you have committed sin. And one of those commandments is to: (Ex.20:8) Remember the Sabbath day, to keep it holy. That’s why Jesus went to church on the seventh day; it is a sin to say that Sunday is the Christian Sabbath, because it is not Christ like! Just like it’s a sin to steal, kill, and commit adultery and so-forth. This is the day He would naturally have observed, because He originally made the Sabbath by resting and ordained that it be kept holy from that time forward.
