there's no need to expose sin, sinners have no judgement of sinners. how about your sins be exposed? or would you rather they be covered? Jesus didn't and doesn't expose sin, He covers it, in that the Father sees His through His Beloved Son rather then Adam.Sacrifice meaning taking the good with the bad, or just accepting the bad. Some people only get in relations providing that something is in it for them.
If one's attempts to turn the other cheek without knowing why God intended this to be the best policy, the expected results, which is to expose the culprit's sin, and keep yourself innocent, may backfire, and instead, the guilty party may become empowered to insult and abuse further.
Noah's curse stuck because the Lord his God agreed:
Gen 9:21 And he drank of the wine, and was drunken; and he was uncovered within his tent.
Gen 9:22 And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without.
Gen 9:23 And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father's nakedness.
Gen 9:24 And Noah awoke from his wine, and knew what his younger son had done unto him.
Gen 9:25 And he said, Cursed be Canaan; a servant of servants shall he be unto his brethren.
Gen 9:26 And he said, Blessed be the LORD God of Shem; and Canaan shall be his servant.
Jesus didn't come to find sin in the sinner He came to deliver the faithful.
