At this time, let me point out the difference between "Jesus Christ the Man": the bearer of our sins, and "Jesus Christ the Word": the God incarnate; a distinction that is seldom made by believers, but crucial to fully understanding Jesus' purpose on earth.
In John 1: 1-14 we read in part, " In the beginning was the Word, and the Word was with God, and the Word was God... And the Word was made flesh, and dwelt among us..."
From this passage we know that "Jesus the Word" was present at the beginning of all creation, much earlier than "Jesus the Man" who was born in 4 BC. With the difference between the two established by the particular time each came into existence, I will now add that we knew "Jesus the Word" through "Jesus the Man" when the two became one.
For three years, "Jesus the Man", preached the gospel to all who would listen to him, revealing to them the power of the Spirit of the "Word" by what he said and the miracles he performed (Matthew 11:4-5).
You may ask, if there is a difference between "Jesus the Word" and "Jesus the Man", then whom should the believer worship? Who of the two is more important in our salvation?
The answer to your question is found in John 6:63. "The Spirit gives life; the flesh counts for nothing. The words I have spoken to you are Spirit and they are life." Here "Jesus the Man" is informing us he is the vessel through whom the "Spirit of the Word" speaks. Without the Spirit he, being flesh, is nothing.
Therefore, if our paramount concerns are to be happy on this earth, and salvation in the afterlife, we should give our love and devotion to the Spirit by practicing the Word in our daily lives.
