Is there no physical representation of the actions of the Holy Spirit? In this case the sacrament of penance. Has the Christ left us with only the a, b, and can to go on? Can one on Earth not lose their sanctifying grace through committing mortal sin? Or do you posit that they never had this sanctifying grace if they could choose to commit mortal sin? If this is the case, could one chosen by God to be sanctified ever choose sin?
