Charles Ellicott Commentary 2 Timothy 1:11

"whereunto I was appointed a preacher, and an apostle, and a teacher." — 2 Timothy 1:11 (ASV)

Whereunto I am appointed a preacher...—To this—that is, to preach the gospel referred to in the previous verse. (On these titles see 1 Timothy 1:12; 1 Timothy 2:7.) In all his deep humiliation, a solitary prisoner awaiting death, deserted by his friends, St. Paul, with solemn emphasis, rehearses the titles of dignity which, by his Master’s appointment, he possessed in the Christian Church.

The poor prisoner, waiting his summons to a painful death, wished his last charge to go forth with all the authority of an Apostle, adding, however, in the next verse, that his present sufferings were brought upon him because of this very position in the Christian community to which his Master had called him.
