Take Me To Post Comment Form We know that God sanctified (made holy) and commanded that the seventh day (sunset Friday until sunset Saturday) be set aside for man to worship God on, back in Eden. Adam and Eve were not Jewish. He repeats this commandment as written in His Ten Commandments given to Moses upon Mt. Sinai. Finally, it is repeated in the Book of Revelation. If all men have sinned and come short the glory of God, how can man who has sinful nature make holy any day? And, why does most Christian churches worship on a day (Sunday), that God has not made holy Himself and commanded all men to worship Him on? Are not His Ten Commandments immutable as He states in the Book of Revelation, Chapter 14, verse 12?
