II Timothy 1:8-12 Not Ashamed.
Paul told Timothy to not be ashamed of the gospel or of him for being imprisoned for preaching it (Cf. Eph. 3:1). The gospel is the power of God, even in the midst of suffering for it (v. 8 Cf. Rom. 1:16). It is God who saves us and not we ourselves, and He has “called us with a holy calling” (v. 9a). This holy calling is an effectual one, and because it is effectual one it is also a call for us to be holy. It must be God making it effectual because it is “not according to our works, but according to His own purpose and grace which was given to us in Christ Jesus before time began” (v. 9). We have been effectually called “according to His purpose” (Rom. 8:28). This purpose was before time began, in the counsels of eternity, and based solely on grace.
This mystery which was once hidden was “revealed by the appearing of our Savior Jesus Christ, who has abolished death and brought life and immortality to light through the gospel” (v. 10). This is also why Paul was not ashamed of the gospel, because in the gospel of Christ we are saved from death to live forever with Him. He was “appointed a preacher, an apostle, and a teacher of the Gentiles” (v. 11). Paul did not assume these roles, and although the apostolic office has ceased, God still appoints preachers and teachers to make known the gospel to all nations. He wasn’t suffering for his own misdeeds, he was suffering for the sake of the gospel, of which he was not ashamed (v. 12a Cf. Acts 9:16). This hope rested on the one he believed in, and was persuaded that he could commit everything “to Him until that Day” (v. 12b).
