John Stott's commentary on 2 Timothy is simply brilliant. Fit for the layman's devotional time (or perhaps for the Bible study leader) this short (~100 page) work is an excellent supplement to Paul's final words to the church. As with every good commentary, its strength is in revealing the beauty, meaning, power, and command of the Scripture.
In Stott's commentary I was confronted with my own presuppositions of the text. For one example, 2 Tim 2:13 - "if we are faithless he remains faithful - for he cannot deny himself". Stott reveals that, as this links with the preceding verse (12b: "if we deny him, he also will deny us"), Paul is not saying that he remains faithful to us (however true), but is instead saying that in his 'denying' of those who 'deny him', he is faithful to his own character.
However, what I most benefited from is Stott's ability to stoke our imagination and emotions. This was especially true in his commentary on the fourth chapter, as Stott reveals to us Paul's emotional heart and need for friends before his execution. In this I found the links with Gethsemane convincing, painful, and humbling. Stott helped me to slow my reading and meditate on the emotional turmoil Paul experienced in this time, yet also his abounding hope in the Lord, who will bring him "safely into his heavenly kingdom" (4:18).
