All four Gospels center their message around the identity of Jesus, who He is, and what He has done.
It is important, therefore, to understand who Jesus is, especially in relation to His titles as “Christ” and “Son of God.”
This is especially true when studying the Gospel of John, since John’s purpose in writing was to get people to believe that Jesus is the Christ, the Son of God (John 20:31). If people receive eternal life by believing that Jesus is the Christ, the Son of God, it is vitally important to understand what these terms mean, and what must be believed about Jesus so that we can be sure we have everlasting life.
“Christ” and “the Son of God” do not require divinity
Many people believe that the terms “Christ” and “Son of God” refer to the divinity of Jesus – the fact that He was God. While that certainly has been a popular view in the past, and is the “traditional” view, more and more students of Scripture are realizing this view does not fit all the Biblical data.
Instead, the terms seem to refer to the role or function of someone who is being used by God in a special way to carry out God’s will on earth. I am studying this entire concept more, but right now, here is what I believe:
The terms “Christ” (or “Messiah”) and “Son of God” did not originally refer to someone who was divine, but to someone who had a special relationship with God and was therefore given a God-appointed task, which was often related to some sort of deliverance. However, as Jesus performed His ministry as “the Christ, the Son of God” the terms grew in significance to include the idea that the God-appointed task of Jesus required Him to be God in the flesh. The Gospel writers (especially John) emphasized the divinity of Jesus to prove that everlasting life is freely given to those who believe in the name of Jesus for it.
What does this mean for John 20:31?
The Gospel of John is often seen as “the only evangelistic book of the Bible.” I am not completely convinced that this is the case. In fact, I think every single book of the Bible is “evangelistic” but this is primarily due to how I understand the word “evangelism” than anything else.
I believe that John, in his Gospel, is trying to get people to see that Jesus is God, and is possibly trying to instill more meaning into the terms “Christ” and “Son of God” than the average person in the first century would have understood or immediately grasped.
In other words, one of the primary purposes of John is to impregnate the terms “Christ” and “Son of God” with new meaning and significance that cannot be used of any other human throughout history.
If this is true, John is not trying to teach that believing that Jesus is God is how a person receives eternal life, but that believing that Jesus is God brings a person to believe in Jesus for everlasting life. There is a vast difference.
Conclusion
I do believe that Jesus is God, and I do believe that some of the later uses of the term “Christ” and “Son of God” refer to the Divinity of Jesus. I do not believe, however, that to receive eternal life, one must grasp and understand the Divinity of Jesus, but simply that He is the one who gives them eternal life. Of course, who would believe this without understanding that Jesus is God?
I sometimes hear pastors say that they don’t have systematic theology; they have pastoral theology.

Jennie Yabroff reports in Newsweek that “After A. J. Jacobs spent a year reading the Entire Encyclopedia Britannica for his book “The Know-It-All,” he figured he had the yearlong experiment thing down. How much harder coudl it be to follow every rule in the Bible? Much, much harder, he soon discovered, as he found himself growing his beard, struggling not to curse, and asking strangers for permission to stone them for adultery.”
