I was first alerted to this in the NIV footnote of that verse:
We pray this so that the name of our Lord Jesus may be glorified in you, and you in him, according to the grace of our God and the Lord Jesus Christ.[a]
Footnotes: [a] Or God and Lord, Jesus Christ
... that the name of our Lord Jesus Christ may be glorified in you, and ye in him, according to the grace of our God and Lord Jesus Christ.
(Though a comma before "Jesus" would make all the difference here.)
How clear is it from the original text what Paul (and Silas and Timothy) intended here? Are they calling Jesus divine?
