A close inspection of Paul's "swan song" in 2 Timothy shows at least four things occupying Paul's mind before his impending death.
1. The judgment seat of Christ: 1:12 (against that day), 1:18 (in that day); 2:12 (we shall reign with him); 4:8 (crown of righteousness...in that day), 4:16 (laid to their charge).
2. Eternal security: 1:12, 2:13, 4:18
3. Apostasy; opposition to the truth: 1:16; 2:16-18; 3:8-9; 4:1-4, 10, 14, 16
4. Suffering for the Lord: 1:8, 12; 2:3, 9, 12; 3:10, 12; 4:5
The present realities of apostasy, opposition, and suffering are balanced with the prospects of eternal security and rewards at the judgment seat of Christ (Rom. 8:18, 2 Cor. 4:17, etc.). Even so, come, Lord Jesus!
