Preach the word!

2 timothy 4:2
Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching

Preach the word is one of the many things this chapter encourages believers to do. Hence we are called to preach and we do so at different extent. It does not say we have to get recognition for our ability to preach nor any kind of certification. When we are grounded in the word, the Holy Spirit would help us overcome other obstacles so that His word is made known.
