Isa. 6:5 ¶ Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts.
He saw himself just as he saw all other men around him - "unclean" before God.
Lu 5:8 When Simon Peter saw it, he fell down at Jesus’ knees, saying, Depart from me; for I am a sinful man, O Lord.
1Ti 1:15 This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.
Ps 39:5 Behold, thou hast made my days as an handbreadth; and mine age is as nothing before thee: verily every man at his best state is altogether vanity. Selah.
Ps 130:3 If thou, LORD, shouldest mark iniquities, O Lord, who shall stand?
Job 9:20 If I justify myself, mine own mouth shall condemn me: if I say, I am perfect, it shall also prove me perverse.
1 Jn. 1:8 ¶ If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Rom. 7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
It can be successfully argued that the vast amount of scriptures above were spoken by professed men of God about how they perceived their own personal condition in regard to sin. .
In direct contrast, the pharisees and sadducees who represented the lost but relgious professors consistently perceived thier own condition as living above sin.
Lu 18:11 The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican.
Jer 2:35 Yet thou sayest, Because I am innocent, surely his anger shall turn from me. Behold, I will plead with thee, because thou sayest, I have not sinned.
Isa 65:5 Which say, Stand by thyself, come not near to me; for I am holier than thou. These are a smoke in my nose, a fire that burneth all the day.
Mt 19:20 The young man saith unto him, All these things have I kept from my youth up: what lack I yet?
Luke 15:29 And he answering said to his father, Lo, these many years do I serve thee, neither transgressed I at any time thy commandment: and yet thou never gavest me a kid, that I might make merry with my friends:
I believe this contrast is true today. Only the religious lost professors perceive their own personal condition as sinless while true believers perceive their own personal condition as still sinful.
Significantly the righteous are not describing their POSITION due to justification but rather their own unglorified condition. They are not expressing what they are "in Christ" but what they are in their own unglorifed condition personally..
