I already answered this through the scriptures. But here it goes again, the day is about focusing on Christ, putting away all secular activities. Going to church, studying the bible, reasoning with the scriptures, spending time in prayer and in nature, appreciating all the things God did for us without us, spending time in fellowship with others talking about what Christ has done for us. The Sabbath is meant to be a blessing, and it is. One day when the saints get to heaven instead of celebrating the Sabbath in His Spirit, the Sabbath will go back to how it was at Creation, coming before the Lord to worship Him in His presence. Isa 66:23 I can't even imagine what that will be like. I do believe those who oppose God's Sabbath now, would not be so happy in heaven, because He says the Sabbath continues. I don't think God will force anyone to be miserable for eternity so I believe His Judgement is a Judgement of love.
