I am not sure what help you require as the Sabbath was a Jewish belief. Many Christian's honor it as a day of rest and refocusing on matters of belief.
"Therefore do not let anyone judge you . . . with regard to a religious festival, a New Moon celebration or a Sabbath day. These are a shadow of the things that were to come; the reality, however, is found in Christ" (Colossians 2:16-17). "And Jesus, when rebuked by the Pharisees for plucking grain from a field on the Sabbath, criticized those who made a fetish of Sabbath observance, insisting, "The Sabbath was made for man, not man for the Sabbath" (Mark 2:27).
I can't look for other places because everything else I agree with them. No hell, no trinity, no holidays, no blood,etc which most other places don't follow.
This statement would indicate to me that you have not learned 'the truth about the truth' which is simply that the WT has always gotten just about everything wrong. You mentioned No Hell and Trinity...... those non beliefs were lifted from the Adventist religions by Pastor Russell.
No blood........... well what did Jesus say about blood? Short answer.........nothing. But the WT was convinced that a transfusion was eating blood. Medically speaking it has nothing to do with eating. It is a transplant.
How about Armageddon? Jesus never mentioned it! The Society sold gullible believers that they could live through that battle or at worse be resurrected to a paradise earth (built over the bones of billions of people). Higher education? Jesus waited to get baptized until he was 30 so that he was thoroughly educated in the scriptures of his day.
Before you make the Sabbath your be all........... get educated about the WTBTS. Start with research on their huge Pedophile issue.
It was Jesus who said "Don't hinder the children....allow them to come to me." He didn't say 'oh by the way......... we have to hide sexual abuse of children from the authorities.'
