The emphasis of LS theology is wrong.
It is based upon the works of man and if that man is worthy of being called a Christian and/or can maintain his standing before His Lord.
LS teaching is based on a human unknowable commodity: the heart of a man.
Was Jesus still Peter's Lord when he denied Him with curses?
The emphsis is upon the Lord. Only God can look upon the heart.
On the other hand there will be those who have called Him "Lord, Lord" but are/were the workers of iniquity all along.
Again, ultimately LS theology has to deal with sinning Christians and what to do with them.
Jesus forgives them. 1 John 1:9.
OR
He corrects them
Revelation 3:19 As many as I love, I rebuke and chasten: be zealous therefore, and repent.
It is His perogative.
When someone makes an unreasonable demand (publicly or privately) of a babe in Christ, that one may himself find that the Lord of that babe will measure them with their own yardstick.
Matthew 7:2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
James 2
12 So speak ye, and so do, as they that shall be judged by the law of liberty.
13 For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment.
