Sin and Paul

Romans 7
24 O wretched man that I am! who shall deliver me from the body of this death?

Jamieson Faussett Brown
But the language is not that of a sinner newly awakened to the sight of his lost state; it is the cry of a living but agonized believer, weighed down under a burden which is not himself, but which he longs to shake off from his renewed self.

Here, Paul, his salvation assured, and an Apostle of Jesus Christ, agonizes over his earthly existence. This is one of those passages well worth a life time of meditation.

The best insight from the above is John Gill's description of Paul as "a living but agonized believer."

Isaiah 6
5 Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts.
