Paul said those that partake of the vile sins of the flesh like murder, rape, fornication, lying, stealing, extortion, idolatry, adultery, profane language, covertness, gossiping busy bodies, vile jesting, riotous, despisers of those that to good, etc. will not inherit the kingdom of God...Their were many people mentioned in the bible who were not sinners. Were they as perfect as Jesus? No...They had sins of ignorance, human flaws, not all perfect knowledge, a moment of doubt, but I can guarantee you that Job had no vile sins of the flesh that would disqualify him, nor did Zacharias and Elisabeth. Yet we know despite of Zacharias being perfect and keeping ALL the commandments of God he still had sins of ignorance and a moment of doubt, so he was chastised by God and spoke not for 6 months until John was born....God does not chastise for willful sin. The day of atonement in the OT was not for wilful sins of the flesh, those people were not around for the day of atonement. None qualify their statement when using the loose term "sinless perfection", they seem to imply that one has to be as perfect as God to be sinless. That's simply not true, the bible is full of perfect people that NEVER engaged in the vile sins of the flesh...Joseph, Hana, and Daniel are good examples but they were not as perfect as Jesus, they just obeyed God with all there own mind, heart, and soul, not Jesus's mind, heart, and soul. One is only accountable to the measure they have not someone else's measure..
Who are you in the parable of the Pharisee and the Tax Collector? I'm the tax collector; and I thank God He wants me to be perfect, but does not condemn me for being imperfect.
Grace; it's the essence of Jesus' mission on Earth, yet 2000 years later people are still trying to snuff it out like a cigarette butt. The shame of it all.
