Paul has just explained how all of mankind is guilty before God, from the unrighteous to the self-righteous, the religious to the non religious, from the Jewish to the gentile, it doesn’t matter what’s your stance on life you are guilty before God without a right relationship in accordance to scripture with Jesus. I have to say in accordance with scripture as we live in a day where people profess to serve Jesus but live a lifestyle based on their personal preferences, instead of on what God’s Holy Word has said is acceptable to Him.
