Is that what MacArthur says?
'John MacArthur, whose book The Gospel According to Jesus lays out the case for lordship salvation, summarizes the teaching this way: “The gospel call to faith presupposes that sinners must repent of their sin and yield to Christ’s authority.” ' Quoted from Got Questions.
He does not use the term "Lordship Salvation", which apparently has been created by his opponents, as though it is incorrect. But it does not matter what MacArthur says. What does the Word of God say?
Now notice what Peter said on the day of Pentecost:Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ. (Acts 2:36)
For Jews, "Lord" literally meant "God" and therefore they substituted "Adonai" (Lord) for YHWH (Yahweh God). So Peter was telling the Jews that Jesus of Nazareth was Lord and God, and they must totally submit to His authority.
And Paul says that all sinners must call upon Jesus as "LORD" in order to be saved (Romans 10):
9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11 For the scripture saith, Whosoever believeth on him shall not be ashamed.
12 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
13 For whosoever shall call upon the name of the Lord shall be saved.
To confess "the Lord Jesus" is to publicly acknowledge that He is Lord of your life from here on. This is BIBLICAL Lordship Salvation, so anyone who opposes this opposes God and Christ.
