Anyway, the OP should've defined the term, "Lordship Salvation".
Those claiming Lordship Salvation is heresy are saying once we are born again, we have no obligation to be obedient to the Lord because they follow Antinomianism believing we can live any way we so desire... even live in sin... and we will still be saved.
They reject the idea that only those that are led by the Spirit of God are the children of God (Romans 8:14) and do not understand the New Testament teaches we are to live under the Law of Christ (Galatians 6:2, 1 Corinthians 9:21, James 2:12, James 1:25, Romans 8:2)
They fail to understand that salvation is only applicable to those that turn from their sin and walk with the Lord abiding IN Christ which is what man is called to (Romans 8:29)
They get mad and claim we are not called unto good works and if we do evil works (live in sin, rejecting the leading of the Holy Spirit) we are still saved rejecting scripture like these:
Ephesians 2:10
For
we are his workmanship, created in Christ Jesus unto good works, which
God hath before ordained that we should walk in them.
Galatians 6:9-10
And let us not be weary in well doing: for in due season we shall reap, if we faint not.
As we have therefore opportunity,
let us do good unto all men, especially unto them who are of the household of faith.
Hebrews 13:16
But to
do good and to communicate forget not: for with such sacrifices God is well pleased.
Luke 6:35
But love ye your enemies, and
do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil.
Matthew 7:18-20
A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
Wherefore by their fruits ye shall know them.
Romans 2:5-11
But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God;
Who will render to every man according to his deeds:
To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
For there is no respect of persons with God.
1 Timothy 6:17-19
Charge them that are rich in this world, that they be not highminded, nor trust in uncertain riches, but in the living God, who giveth us richly all things to enjoy;
That they do good, that they be rich in good works, ready to distribute, willing to communicate;
Laying up in store for themselves a good foundation against the time to come, that they may lay hold on eternal life.
Psalm 34:14
Depart from evil and do good; Seek peace and pursue it.
2 Timothy 2:20,21
But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour.
If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work.
James 2:14-20
What doth it profit, my brethren,
though a man say he hath faith, and have not works? can faith save him?
If a brother or sister be naked, and destitute of daily food,
And one of you say unto them, Depart in peace, be ye warmed and filled; notwithstanding ye give them not those things which are needful to the body; what doth it profit?
Even so faith, if it hath not works, is dead, being alone.
Yea, a man may say, Thou hast faith, and I have works:
shew me thy faith without thy works, and I will shew thee my faith by my works.
Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
But wilt thou know, O vain man, that faith without works is dead?
James 3:13
Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom.
1 Peter 3:10-12
For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile:
Let him eschew evil, and do good; let him seek peace, and ensue it.
For the eyes of the Lord are over the righteous, and his ears are open unto their prayers: but
the face of the Lord is against them that do evil.
2 Corinthians 9:8
And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things,
may abound to every good work:
Colossians 1:9,10
For this cause we also, since the day we heard it, do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding;
That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God;
2 Timothy 3:16,17
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
That the man of God may be perfect, throughly furnished unto all good works.
