This message begins by looking at the shame that is inevitably linked with the Gospel. But goes on to show the power of the Gospel to save, because of the Grace of God. Paul however does not leave Tim or us in some mystical situation rather he shows that God has appointed him to 3 positions in order that the Gospel might be made known.

8 Therefore do not be ashamed of the testimony about our Lord, nor of me his prisoner, but share in suffering for the gospel by the power of God, 9 who saved us and called us to[a] a holy calling, not because of our works but because of his own purpose and grace, which he gave us in Christ Jesus before the ages began,[b] 10 and which now has been manifested through the appearing of our Savior Christ Jesus, who abolished death and brought life and immortality to light through the gospel, 11 for which I was appointed a preacher and apostle and teacher, 12 which is why I suffer as I do. But I am not ashamed, for I know whom I have believed, and I am convinced that he is able to guard until that day what has been entrusted to me.[c]
