Obedience to God's will is something which we all have to learn over a period of time. Christ also had to go through this process of learning obedience to his Father, as any son has to. "Though he were a Son, yet learned he obedience (i.e. obedience to God) by the things which he suffered; and being made perfect (i.e. spiritually mature), he became the author of eternal salvation" as a result of his completed and total spiritual growth (Heb. 5:8,9). Phil. 2:7,8 (further commented on in Digression 27) records this same process of spiritual growth in Jesus, culminating in his death on the cross. He "made himself of no reputation, and took upon him the form (demeanour) of a servant...he humbled himself and became obedient unto...the death of the cross."
Kutii mapenzi ya Mungu ni jambo lingine yanatupa sote kujifunza kwa kipindi chote cha wakati. Naye Kristo ilimpasa kupitia njia ya kujifunza kumtii Baba yake, kama ipasavyo mwana yeyote."Na ingawa ni mwana, alijifunza kutii (yaani kumtii Mungu) kwa mateso hayo yaliyompata; naye alipokukwisha kukamilishwa (yaani, akiisha kua ki- roho), akawa sababu ya wokovu wa milele."Kwa matokeo yake kamili ya kukua kiroho (Ebr 5:8,9), Wafilipi 2:7,8 (zaidi limefafanuliwa katika somo la kuacha kitambo kilichoandikwa sehemu ya 27) imetoa taarifa ya hii njia moja ya kukua Yesu kiroho, na kuishia kwenye mauti ya msalabani."Alijifanya hana utukufu, akatwaa namna ya mtumwa (yaani kwa mwenendo)……. alijinyenyekeza akawa mtii….. mauti ya msalaba."Msemo uliotumika hapa unaeleza jinsi gani kwa fahamu Yesu hakugeuka katika maendeleo ya kiroho, mwenyewe akijinyenyekeza zaidi na zaidi, kwa sababu hiyo"akawa mtii"kufanya mapenzi ya Mungu ili afe msalabani, Hivyo basi"akakamiliswa"kwa kuitikia kwa usahihi mateso yake.
