Honor My Sabbath to keep it holy??
Why follow a commandment regarding tattoos? (if ignoring any other in the 5 Books of Moses?)
God’s Law does not change according to the whim of the moment. It serves three, at least, purposes: it reveals the nature of God since it stems from Him, it shows us that we cannot obey God perfectly and that we need a Savior, and it shows us how we can please God, i.e. what behaviors would make Him happy.
To be sure, we do not honor the Sabbath the way we should, but we can try, confess when we become aware of our sin, and receive forgiveness. And, try again. But our failure, does not give us license not to try, and especially not to disobey. We should try all the more.
