I would like to know what the expression "your feet are on the Rock" means. I think it's about religion and I was wondering if it was the same as "your conscience is clear" ? I think I understood that it's about having served the Lord and not having to worry about paradise, but could you give me a more precise definition?
Without more context I'd guess it referred to having a sound foundation for everything you do. Jesus is credited, in the Vulgate, with making a pun on the name "Peter": Tu es Petrus et super hunc petrum aedificabo ecclesiam meam. ("... upon this rock I will build my church"). I don't know whether this pun would have worked in Aramaic.
Of course, if you have a sound foundation for everything you do you are bound to have a clear conscience.
