Whereas in John 3, we are given a passage on how to be born again, which says simply to believe in Christ; in Romans 10 we are given a passage saying, "For whosoever shall call upon the name of the Lord shall be saved." But we also find in the same chapter the words "How shall they call upon on him in whom they have not believed?"
This then is the question: Are we saved by believing, or by calling upon the name of the Lord (the Lord Jesus)? And exactly what does it mean to "call upon the name of the Lord"?
Excellent thread topic!!
John 3:15 (NASB)
so that everyone who believes will have eternal life in Him.
John 3:15 (NET)
so that everyone who believes in him may have eternal life."
The Greek word translated "in" is "eis" which means "into." So if the phrase arrangement is best in the NASB, then it would read have eternal life within Him. And if the arrangement is best in the NET (my choice) then it would read everyone believing into Him, indicating a spiritual relocation is in view.
The key point is that it is God who credits an individuals faith as righteous faith or not, and if credited as righteous faith, then God transfers the person out of the realm of darkness into Christ.
This is a fundamental part of the gospel.
And if we accept this biblical truth, then "calling on the name of the Lord" is at least a facet of the faith God credits as righteous faith. I think the idea is turning from trusting in ourselves and relying solely on Christ for our salvation. The "name" of the Lord refers to the attributes and characteristics of Christ that we rely upon such as God in the flesh, the Lamb of God, our Savior and so forth.
