As a point of order, I wish to note that while Lordship Salvation is called heresy by some, this does not mean that teaching a false doctrine mean one is unsaved. It just means they are gravely mistaken on said doctrine.

In an excellent start to an article, we see 12 quotes by leading pastors and teachers on the topic:

A. The problem:

On the one hand there are those who insist that salvation is God’s gift and that trust in Christ is the only requirement for salvation. On the other hand, there are respected pastors and theologians who teach that unless an individual submits also to the Lordship of Christ at the moment of salvation, he is not really saved.

B. The positions:

1. Salvation by grace through faith alone:
2. Curtis Hutson in his book, Salvation Crystal Clear, has a chapter entitled “Lordship Salvation, A Perversion of the Gospel.” He begins with the following warning: “Lordship salvation is an unscriptural teaching regarding the doctrine of salvation and is confusing to Christians.” Hutson calls Lordship salvation another gospel which contradicts the teaching of salvation by grace through faith” (p. 302).
3. Charles Ryrie cautions that “To teach that Christ must be Lord of life in order to be Savior is to confuse certain aspects of discipleship and confuses the gospel of the Grace of God with the works of men.” (Balancing the Christian Life, p. 178).
4. Lewis Chafer writes that Lordship salvation is a seemingly pious but subtle error that in addition to believing in Christ “the unsaved must dedicate themselves to the will of God” (Systematic Theology, III, 384).
5. Zane Hodges clearly distinguishes between salvation and discipleship. Eternal life is free. Discipleship is immeasurably hard. The former is attained by faith alone; the latter by a faith that works (The Hungry Inherit. p. 114, underscore in the original).
6. Lordship Salvation:
7. J. I. Packer rejects the idea that all men “have to do is to trust Christ as sin bearer . . . they must also deny themselves and enthrone him as their Lord.” (Evangelism and the Sovereignty of God, p. 89).
8. Walter J. Chantry says that salvation without Lordship is impossible: “Practical acknowledgment of Jesus’ Lordship, yielding to His rule by following, is the very fibre of saving faith. It is only those who ‘confess with the mouth the Lord Jesus’ (Romans 10:9) that shall be saved . . . Without obedience, you shall not see life! Unless you bow to Christ’s sceptre, you will not receive the benefits of Christ’s sacrifice.” (Today’s Gospel Authentic or Synthetic? p. 60, underscore in the original). His words concerning those who preach simple faith in Christ are very strong: “This heretical and soul-destroying practice is the logical conclusion of a system that thinks little of God, preaches no law, calls for no repentance, waters down faith to ‘accepting a gift,’ and never mentions bowing to Christ’s rule or bearing a cross.” (p. 68).
9. John R. Stott suggests “that it is as unbiblical as it is unrealistic to divorce the Lordship from the Saviorhood of Jesus Christ” (Eternity, Sept. 1959, p. 37).
10. A. W. Tozer labels the view of salvation by grace alone a notable heresy and a false teaching (I Call It Heresy! p. 9,19).
11. James Montgomery Boice calls the concept of salvation through faith alone A defective theology. This kind of faith is directed to one who is a false Christ (“The Meaning of Discipleship”, Moody Monthly, Feb. 1986, p. 34, 36).
12. John MacArthur champions Lordship salvation in his recent book, The Gospel According to Jesus. He attacks dispensationalists in general and Chafer, Hodges, and Ryrie in particular for “wrongly dividing the Word of Truth” (p. 197). “No one can come to Christ on any other term” than full commitment (p. 197). In his book, The Parables of the Kingdom, MacArthur writes that “there is a transaction made to purchase salvation, but it’s not with money or good works. The transaction is this: You give up all you have for all He has” (p. 108). How does one receive salvation? “You give up all that you are and receive all that He is . . . A person becomes saved when he is willing to abandon everything he has to affirm, that Christ is the Lord of his life” (p. 109). Even in our Regular Baptist circles, Lordship salvation has become an issue.
13. John Baylo equates the saviorhood of Christ with His Lordship. He holds that “saving faith properly understood always involves trusting Christ with one’s life. . . confidence in Christ to both save and manage one’s life . . . superficial faith never saved anyone” (Baptist Bulletin, February, 1987, p. 7).

This is the key paragraph in that article:

• Being a Christian means following an invitation. Being a disciple means forsaking all. To confuse these two aspects of the Christian life is to confound the grace of God and the works of man, to ignore the difference between salvation and sanctification. The gospel of grace is Scriptural. The Gospel that adds the works of man to salvation is a counterfeit Gospel.

I just wish to note that the same people that talk to me about the “Reformation” [read here: new Calvinists] upholding the SOLAS is full of it. And is why I say TULIP rejects the SOLAS…. all of TULIP.

Lordship Salvation (“perseverance”) inserts a myriad of works related issues into the mix. So much so, J.VERN called it a heresy!

BTW, I became aware of the J. Vern video because of this presentation over at the BIBLE PLACE. However, this presentation by the Bible Place is the one that showed me how people get the kingdom age mixed up. It is longer, s be prepared to settle in:

Another quote to make the point is this one:

• It may even be said that Lordship Salvation throws a veil of obscurity over the entire New Testament revelation. In the process, the marvelous truth of justification by faith, apart from works, recedes into shadows not unlike those which darkened the days before the Reformation. What replaces this doctrine is a kind of faith/works synthesis which differs only insignificantly from official Roman Catholic dogma.

Zane C. Hodges, Absolutely Free: A Biblical Reply to Lordship Salvation (Corinth, TX: Grace Evangelical Society, 2014)

Pastor Andy Woods brought up a paper my Dr. Minirth? Here it is for the reader.

From what I hear through the grapevine (I live a stones throw away from Masters College and live in a town where everyone knows or went to at some point [church goers at least] to Grace Community) John MacArthur became frustrated with his congregation early in his career. He went on a sabbatical and got into the writings of the Puritans. This is where he started to align with the 5-points and his Lordship Salvation idea. And he obfuscated the Christians birthright.

And so, Johnny Mac brought that uncertainty of the Puritan’s salvation into his fold. More on the Puritans here:
