ISB ~ 2 Timothy 1 v12

whom I have believed:Christ, whom Paul calls his “Savior” (1:10).

that Day:An abbreviated reference to the Day of Judgment (1:18; 4:8).

entrusted to me:Paul did not invent the gospel, nor did he receive it from the original band of apostles. It was given to him directly from the risen Jesus (Gal 1:11-12).
