Deputy Dog Wow good thread.
Stephen I think you're on to something.
"not having a righteousness of my own that comes from the law, but that which is through faith in Christ—the righteousness that comes from God and is by faith."
Cool! Here's some more on the same theme :)
Romans 10:1-13 (New International Version)
1 Brothers, my heart's desire and prayer to God for the Israelites is that they may be saved. 2 For I can testify about them that they are zealous for God, but their zeal is not based on knowledge. 3 Since they did not know the righteousness that comes from God and sought to establish their own, they did not submit to God's righteousness.
Paul is talking about the Jews but these verses describe the WT and JWs perfectly.
4 Christ is the end of the law so that there may be righteousness for everyone who believes.
Christ is the only righteousness we can have, and the only thing we can do to obtain it is belief in Him.
5 Moses describes in this way the righteousness that is by the law: "The man who does these things will live by them." 6 But the righteousness that is by faith says: "Do not say in your heart, 'Who will ascend into heaven?'" (that is, to bring Christ down) 7 "or 'Who will descend into the deep?'" (that is, to bring Christ up from the dead). 8 But what does it say? "The word is near you; it is in your mouth and in your heart," that is, the word of faith we are proclaiming: 9 That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.
Sincere belief in the Lordship, and physical resurrection Luke 24:39 of Jesus leads to salvation, nothing else.
11 As the Scripture says, "Anyone who trusts in him will never be put to shame." 12 For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him, 13 for, "Everyone who calls on the name of the Lord will be saved."
The WT twist this key last verse to their own destruction 2 Peter 3:16
The Jesus is Lord 1 Corinthians 12:3 , not "jehovah". The WT falsely insert "jehovah" in their own NWT bible and create a contradiction, see here for example Acts 4:10-12
Blessings,
Stephen
