Well, I've found a few minutes to post.
You know, everyone goes to Romans to explain the Gospel. The "Romans Road" is used by many to give the Gospel, and Romans is used as the theological foundation for any discussion of salvation. However!! Romans explains the Gospel and salvation, but it is not the book designed to teach it to lost people. That book is John's Gospel (20:30-31).
Now, the word "Lord" appears 44 times in the book of John. There are only two places in the book of John where it actually discusses the Lordship of Christ. In every single other instance, it is used as a title for Christ, and then usually in conversation by Christians addressing Christ, not as a condition of salvation.
The first is after Christ washes the disciples' feet in ch. 13. And there the purpose of the discussion is not to get anyone to accept Him as Lord. That is given as a fact. No, it is to teach humility and service to the disciples. Salvation is not in question in this passage.
The second is when He discusses the relationship of servant and Lord in chapter 15. But then he tells them that they have a new relationship with Him, that of friendship!! Salvation is not in question in this passage either.
Some would say that when Thomas calls Christ "My Lord and my God" in 20:28 he was getting saved. But that is speculation. At any rate, even if Thomas was getting saved there, John never tells anyone to believe Christ as both Lord and Savior.
One final note on John. If you will check your harmony of the Gospels, you will find that the strongest passage on the Lordship of Christ in all the Gospels, the one where Jesus tells His disciples to take up their crosses and follow Him, is not in John!! It occurs in Matthew, Mark and Luke, but not in John. So the only book in the NT with a goal of having people believe in Christ does not tell us to take up our cross, deny ourselves, and make Christ the Lord of our lives.
