Mark, a cousin of Barnabas (Colossians 4:10), was an eyewitness to the events in the life of Christ as well as being a friend of the apostle Peter. Mark wrote for a Gentile audience, as is brought out by his not including things important to Jewish readers (genealogies, Christ's controversies with Jewish leaders of His day, frequent references to the Old Testament, etc.). Mark emphasizes Christ as the suffering Servant, the One who came not to be served, but to serve and give His life a ransom for many (Mark 10:45).
Marko, binamu yake Barnaba (Wakolosai 4:10), alikuwa mshahidi wa matukio katika maisha ya Kristo pamoja na kuwa na rafiki wa mtume Petro. Marko aliandika kwa ajili ya watu wa Mataifa, kama vile inavyoelezwa naye kwa kukosa mambo mhimu (Ukoo, mgongano wa Kristo na viongozi wa Kiyahudi wa wakati wake, kurejelea kwake katika Agano la Kale mara kwa mara) kwa Wayahudi wasomi wa nakala yake. Marko anasisitiza Kristo kama mtumishi mteswa, aliyekuja si kutumikiwa, bali kutumikia na kutoa maisha yake kama fidia ya watu wengi (Marko 10:45).
