It is also a fundamental tenet of Christianity that Jesus is the Son of God. If God is not a corporeal (bodily) being, then it is impossible for Him to have a son who was the "image of His person" (Heb.1:3). Further, it becomes difficult to develop a personal, living relationship with 'God', if 'God' is just a concept in our mind, a wisp of spirit somewhere up in the emptiness of space.
Vilevile ni mafunzo ya kwanza ya Ukristo kuwa Yesu ni mwana wa Mungu. Ikiwa Mungu hana umbo, basi haiwezekani yeye kuwa na mwana ambaye alikuwa ni 'Chapa ya nafsi yake' (Ebr 1:3) Tena inakuwa vigumu kuendeleza maisha ya uhusiano wake na mungu ikiwa Mungu ni wazo lililo kwenye akili zetu, Mkusanyiko wa roho mahali popote juu katika anga lisilo na kitu.
