Hi Enrico - sorry if it came across the wrong way but I am not trying to cast judgement on others, but, rather, to share what Jesus Himself said. I know what Paul said also and it does sound sometimes sonewhat conflicting so I am praying for clarity for all of us to understand better. I am trying to bear in mind that only God knows everything and I try to heed the warning in 2nd Peter 3.16 - And also in his eg Paul's epistles, speaking in them of these things, in which are some things hard to be understood, which they that are unlearned (untaught) and unstable wrest, as they do also the other scriptures unto their own destruction.
I know that the law does not save us or make as righteous, as soon Christ became the Sacraficial Lamb the animal sacrafices are no longer necessary. I know Paul said in Galatians 2.21 - I do not frustrate the grace of God, for if righteousness come by the law, then Christ is dead in vain.
I just know that Jesus said - in Matthew 5.17 - Think not that I am come to destroy the law, or the prophets; i AM NOT COME TO DESTROY, but to fulfil. 5.18 - For I say to you - Til heaven and earth pass, one jot or one tittle shall in no wise pass from the law, until all of it be fulfilled.
Jesus also said in Matthew 23.2 - The scribes and the Pharisees sit in Mose's seat. 3 - All therefore they bid you observe, that observe and do, but do not ye after their works for they say, and do not.
I also know that Jesus said that when He returns many will say to Him - Lord, Lord. and He will say to them - depart from me you lawless ones I never knew you. God bless.
