“But these things
Were written
So that you may come
To believe
That Jesus
Is the Christ,
The Messiah,
The Son of God.
That through believing,
You may have life
In his name.”
ταῦτα δὲ γέγραπται ἵνα πιστεύητε ὅτι Ἰησοῦς ἐστιν ὁ Χριστὸς ὁ Υἱὸς τοῦ Θεοῦ, καὶ ἵνα πιστεύοντες ζωὴν ἔχητε ἐν τῷ ὀνόματι αὐτοῦ.
John explained the purpose of this writing at the end of it. He said these things were written (ταῦτα δὲ γέγραπται), so that many people could come to believe (ἵνα πιστεύητε) that Jesus (ὅτι Ἰησοῦς) was and is (ἐστιν) the Christ (ὁ Χριστὸς), the Messiah, the Son of God (ὁ Υἱὸς τοῦ Θεοῦ). Once you believed (καὶ ἵνα πιστεύοντες), then you would have life (ζωὴν ἔχητε) in the name of Jesus (ἐν τῷ ὀνόματι αὐτοῦ). This clearly was a faith document, not a factual explanation about Jesus. Jesus was and is the Messiah, the anointed one, the Christ, the Son of God. The only purpose for this writing was that all might believe that Jesus was the Christ Messiah. Thus, knowing this, you could enjoy eternal life with Jesus. Do you enjoy life in the name of Jesus?
