Understanding that Jesus is fully God and fully man is fundamental to the success of the life of the believer.  The great commission tells us to go and make disciples of all people groups. The disciples that we are instructed to make should be an emulation of the process by which Jesus made disciples.  If we as Jesus followers fail to embrace the humanity of who Jesus was, then our efforts to make disciples will ultimately be short circuited.  While Jesus was indeed God wrapped in flesh, he still relied on the instruction of God the father, the guidance of God Holy Spirit, a lifestyle in prayer and studying of scripture and intentional time in community.  These are the same things that we must rely on if we are to fulfill John 14:12!
