What does John 3:16 really teach?
John 3:16 says, “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”
Many people today use John 3:16 as their primary verse in evangelism. But are they correct in doing so? Well, yes. And no.
As with all verses, John 3:16 must be understood in its context. And the context of this verse is the First Advent of the Lord Jesus Christ. During His earthly ministry, the Lord presented Himself to the nation of Israel as their Messiah. This is critical to understanding and properly applying this verse to our current dispensation of grace.
Now the first half of this verse presents no problems because it presents a universal, transdispensational truth: God loved the world so much that He gave His only Son to provide salvation. So far, so good.
But the problem comes with “whosoever believeth in him should not perish.” What does this verse mean by “believeth in him?” What are we to believe about Him? And what does that belief entail?
In its context, John 3:16 says nothing about the gospel of the grace of God. What was Nicodemus (a Jew under the law in the kingdom program) supposed to believe? That Jesus was the Messiah, that He was the Son of God—and in that context, that belief also included baptism and keeping the law (Matt. 3:8; 5:20; 28:20; Jn. 20:31). Without Paul’s gospel to explain what it is we are believing, no one is saved.
So the “believing” in this verse is not the same “believing” that saves today in the dispensation of the grace of God. That is why people who mistakenly use this verse in evangelism today have to go to Paul’s epistles to explain what it means to “believe in him.”
No one who uses John 3:16 for evangelism stays within its Jewish kingdom context and teaches that “believing in him” means to believe that Jesus is the Messiah and to keep the law. Instead, they start at John 3:16 and then go to Paul’s epistles to explain that “believe in him” means to believe the gospel of the grace of God—which is faith alone in the finished work of Christ on our behalf.
So, is John 3:16 valid to use in evangelism today? Well, only to the point of showing that God loved the world so much that He provided salvation for it through His Son, the Lord Jesus Christ. But after that, you have to go to Paul’s epistles, where the gospel of the grace of God is revealed to find out what “believe in him” means.
