Stop pretending the cup is clean throughout!
Jesus clearly taught that sin starts in the mind which is a matter of the spirit.
This is well before sin becomes a matter of the flesh.
No flesh has ever committed sin without a carnal mind to start with.
Flesh does not commit sin, the person does, and they do so from within first.
Doctrines such as OSAS and Original Sin attempt to justify the outside of the cup while the inside is still wretched.
Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment: But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire. Matthew 5:21-22
Ye have heard that it was said by them of old time, Thou shalt not commit adultery: But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. Matthew 5:27-28
For to be carnally minded is death; but to be spiritually minded is life and peace. Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be. Romans 8:6-7
The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him. Ezekiel 18:20
Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught? But those things which proceed out of the mouth come forth from the heart; and they defile the man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies: These are the things which defile a man: but to eat with unwashen hands defileth not a man. Matthew 15:17-20
Thou blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also. Matthew 23:26
So, stop using false doctrines to justify that the cup is clean throughout when it is filthy on the inside! Clean it already.
