Touchy aren't we? Do you even know what ignorant means? I am very ignorant about many subjects.
By appealing to the OT laws you are showing your ignorance of Christianity and Biblical truth. Read Acts 15 and you will get answers to many of your questions. BTW, I don't own a car.
As to good works that is not the subject of this thread. I got banned from another Christian message board because I posted that I know many gays who practice what the Bible teaches about good works without knowing what the Bible teaches about helping the poor and etc.
