For God so loved the world, that he gave his only Son,
that whoever believes in him should not perish but have eternal life.
– John 3:16 –
While John’s Gospel includes many themes, one stands above the rest: belief that Jesus Christ is the Son of God. In fact, John 20:31 discloses why John wrote his Gospel: “These are written so you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.” Coming right after Thomas’ pronounces his faith in Christ, “my Lord and my God” (v. 28), John reveals his intentions. He desires for you and I to believe that Jesus Christ is the Son of God as the singular way that we might find eternal life.
Belief in John’s Gospel
Once we tune in to John’s emphasis on belief, we discover that the verb ‘believe’ (pisteuo) occurs 98 times in John’s Gospel. Interestingly, the noun ‘faith’ (pistis) doesn’t occur at all. Clearly, John’s Gospel is meant to create faith in its hearers, not just describe what it is. Nevertheless, by paying attention to the way John speaks of believing, it is possible to learn what faith is. And importantly, belief is more than just mental agreement. In fact, when all the promises of eternal life are considered, it becomes apparent that saving faith savors Christ. That is, those who truly believe do far more than merely assent; they approach Christ the way a starving man approaches a feast.
Indeed, in a book that testifies to who Jesus is, the beloved disciple spends ample time considering the nature of saving faith. He indicates that Jesus knew of a faith that did not save (2:23–25) and so he labors in his Gospel to show that saving faith “receives Christ,” “comes to Christ,” “honor Christ,” and “feeds on Christ”—to only name a few descriptors. Although John states plainly in John 3:16 that eternal life is the reward of believing, we will see genuine faith does far more than simply believe. Continue reading
