The grace of God permits for doing good on the Sabbath. It is good you have a job to keep your family. If there is not recourse but to work, do you think Jesus Christ is going to throw you into the eternal lake of fire for doing this? Learn to obey the law in grace, and this will be self-evident to you. You may work if you are obliged to on the Sabbath, but it is still the Sabbath, just keep the day separate, and whenever possible, don't work.
Oh well, it;s impossible for me to keep Sabbath as I have to work so I guess I will hang myself. What's wrong with that I meant Once saved always saved so what do I have to lose?
