This passage comes from chapter 1 of Dr. Lloyd-Jones's book on Romans 6, The New Man published by the Banner of Truth. It is a key point in the epistle. He writes . . .
We are looking at something which has a very direct and immediate connection with the previous chapter, something which arises directly from it.
What was the apostle's theme in chapter 5? It was the theme of assurance and the certainty of salvation. Paul is asserting that our justification guarantees our final redemption in the fullest sense; that if a man is justified by faith, he can be happy about his ultimate salvation. If you are justified, you can be assured that you are going to be sanctified and glorified. If we are justified by faith we 'rejoice in hope of the glory of God'. Or, as we indicated, we find the same leap from justification to glorification as is found in chapter 8, verse 30: 'Moreover whom he did predestinate, them he also called; and who he called, them he also justified; and whom he justified. them he also glorifies.'
