Keep the Sabbath
All I have to say is that after reading Hebrews 4:1-13, I am convinced that I and all lovers of Christ need to keep the sabbath. Also don't forget James 2:10-11 that state "For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. For he that said "Do not commit adultery, said also, do not kill. Now if thou commit no adultery, yet if thou kill thou art become a trangressor of the law."
