Yes, I agree , like the woman adultress that was about to be stoned. Sure at that time none was without sin because none at that time had not believed in Jesus to be saved. before that happened, he had to lay the foundation by preaching and teaching before any could be saved, yes, they had to hear the word, the gospel from heaven first. He told her, where are your accusers, and then he told her to go ,AND SIN NO MORE. You cannot treat sin today like it was before Jesus came,because they had not known the truth yet. All that was saved after Jesus left became righteous,and the gospel was opposed to those that walked in darkness., and preached against sin also. You can't pretend and look the other way as if there is no sin in the world, if you are one of these people, the you make the gospel lose it's strength. We don't condemn,because if we did, no abomination would exist because we would rid the world of them, but instead, we preach against such things as Jesus have told us to do.
