I agree. And no Reformed teacher has ever condoned sin. Recognizing that we remain sinners after conversion is not a condoning of sin or a license to sin. It rather should humble us to depend upon our savior every day to deliver us from our sins of which we are only dimly aware.
Your doctrine is a doctrine of demons because you minimize or ignore the hidden sin that lurks beneath the surface of your behavior - the pernicious sin in your heart which is most often unknown to you. You think that because you've seen the tip of the iceberg in your behavior that you've seen all there is to see of your sin. You believe that if you can white wash your behavior then you can be free of sin. This is a radical diminishing of the demands of God's law - which reach beyond external behavior to the thoughts and intentions of the heart. At the same time it is a radical denial of your own sin.
This is a demonic doctrine because the devil does not want you to recognize or understand your sin and does not want you to live as a repentant, dependent, humble person. He would rather you be a self-righteous, externally righteous Pharisee who will be condemned to hell on the last day.
Perseverance of the Saints and or Once Saved Always Saved leads people into unrepentant sin with the thinking they are saved on some level. They may even think they are being humble by the fact that they know they will sin again soon and yet they confess it to God. Somehow they think the Parable of the Tax Collector is an every day or every week kind of thing (even when the Parable does not say such a thing). However, 1 Timothy 6:3-4 also talks about how if do not agree with the words of Jesus and the doctrine according to godliness, we are proud and we know nothing. James 4:6 says God resists the proud and gives grace to the humble. Admitting sin and not stopping in one's sin is not a humble thing. Would a wife consider her husband humble if he admitted that he was cheating on her and yet he said to her that he just did not think he had any power to stop? Surely not. She would most likely leave him for being unfaithful. No doubt, many Calvinists may think I am weak for appealing to emotion by this example. If the Bible says it is true from their Calvinistic view or slant, then it is true and no appeal to any emotional point will get through. God's Word says it and emotions are just a form of weakness.
What you are not getting is that we are to understand with our heart as a part of being converted. The heart is an emotional thing.
"For this people's heart is waxed gross, and
their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with
their eyes, and hear with
theirears, and should understand with
their heart, and should be converted, and I should heal them." (Matthew 13:15).
"For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death." (2 Corinthians 7:10).
Paul reveals his heart to us about those who he thinks are enemies of the cross.
"For many walk, of whom I have told you often, and now tell you even weeping,
that they are the enemies of the cross of Christ:" (Philippians 3:18).
Paul was weeping over those who were enemies of the cross.
He loved them.
Jesus says,
44 "Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;
45 That ye may be the children of your Father which is in heaven" (Matthew 5:44-45).
"But as he came closer to Jerusalem and saw the city ahead, he [Jesus] began to weep." (Luke 19:41).
“O Jerusalem, Jerusalem, the city that kills the prophets and stones God’s messengers! How often I have wanted to gather your children together as a hen protects her chicks beneath her wings, but you wouldn’t let me." (Matthew 23:37).
Jesus desired His people (the Jews) to be saved, but they wouldn't allow Jesus into their lives so that they could be saved.
The Jews ignored the weightier matters of the Law like love, faith, justice, and mercy.
"Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier
matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone." (Matthew 23:23).
"But woe unto you, Pharisees! for ye tithe mint and rue and all manner of herbs, and pass over judgment and the love of God: these ought ye to have done, and not to leave the other undone." (Luke 11:42).
Anyways, I hope what I have shown by the Scriptures here is that God has a heart and He loves us and He desires us to be conformed to His image and not to the image of the old man or our old life. We have to love. It is not optional, my friend. So I encourage you to seek these matters out more with the Lord within His Word by prayer.
In any event, I am wishing you nothing but good things to you from the Lord Jesus Christ. May you please be well.
