As God is a real, personal being who therefore has feelings and emotions, it is to be expected that He will have some way of sharing His desires and feelings with us, His children, and of acting in our lives in a way that will be consistent with His character. God does all of these things by His "spirit". If we wish to know God and have an active relationship with Him, we need to know what this "spirit of God" is, and how it operates.
Mungu akiwa ni mtu halisi (ieleweke kuwa tunaposoma mtu hatuna maana kuwa ni Mwanadamu) kwa sababu hiyo anayo mawazo na hisia, basi itegemewe kuwa atakuwa na namna nyingine ya kushirikiana mawazo na nia yake pamoja nasi, watoto wake na kwa kutenda kazi katika maisha yetu kwa mfano ambao una tabia ya sifa yake.Mungu anafanya mambo yote haya kwa 'Roho’ yake kama tunataka kumjua Mungu na kuwa na uhusiano wenye matendo pamoja naye, tunahitaji kufahamu jinsi hii " Roho ya Mungu" na namna inavyotenda kazi.
