ISB ~ 2 Timothy 2 v15

the word of truth:The gospel message, which is “heard” through preaching (Eph 1:13; Col 1:5). Uppermost in Paul’s mind is the word of God orally proclaimed (1 Thess 2:13), not the word of God written in the Scriptures (Rom 15:4), though the latter is often central to Christian teaching and evangelism (2 Tim 3:16).
