Faith is the strongest evidence that we have hope of eternal life through the redemption that is in Christ Jesus, our Lord.
1 John 5:1
“Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.”
John 20:31
“But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.”
That is...the knowledge of!
1 John 5:1 (KJV)
"Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him."
1. "Whosoever believeth" (πᾶς ὁ πιστεύων)
The verb πιστεύων (pisteuōn) is a present participle of πιστεύω (pisteuō, "to believe"), which indicates continuous or habitual action. It refers to those who are continually believing or those who have made a decisive, ongoing commitment to the belief that Jesus is the Christ.
"Believeth" in this sense is not just a one-time act but describes a lifestyle of faith—a person who has placed their trust in Jesus and continues to abide in that trust.
2. "That Jesus is the Christ" (ὅτι Ἰησοῦς ἐστιν ὁ Χριστός)
This clause affirms the core of Christian faith: Jesus is the Messiah (the Christ) sent by God. The phrase "is the Christ" denotes identification with the long-expected Messiah of the Old Testament (see Isaiah 9:6–7, Daniel 9:25–26).
3. "Is born of God" (ἐγεννήθη ἐκ τοῦ Θεοῦ)
The verb ἐγεννήθη (egenēthē, "was born") is an aorist passive verb, indicating that this is a completed action initiated by someone else (God), and the subject (the one believing) receives the action. Being born of God implies a spiritual rebirth, a concept associated with regeneration (John 3:3–7). The passive voice indicates that the individual does not regenerate themselves, but rather is regenerated by God.
4. "Every one that loveth him that begat loveth him also that is begotten of him"
"Loveth" (ἀγαπῶν, agapōn) is a present participle, indicating an ongoing action. This love is a natural consequence of being born of God. Those who love God (the Father) will also love those who are born of God (the brethren, Christ and others who belong to Him).
This highlights the inseparable connection between the believer's love for God and love for fellow believers, both of whom are in the family of God.
Faith leads to regeneration (birth from God), and this leads to love for God and His people.
This passage emphasizes that believing in Jesus as the Christ is the foundational evidence that one has been born of God and is part of the divine family.
John 20:31 (KJV)
"But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name."
1. "These are written" (ταῦτα γέγραπται)
The verb "written" (γέγραπται, gegraptai) is in the perfect tense, indicating that these things have been written in the past with lasting effects and continue to be in force. The written word of God (the Scriptures) serves as a testimony to Jesus’ identity and mission.
2. "That ye might believe" (ἵνα πιστεύητε)
The verb "might believe" (πιστεύητε, pisteuēte) is in the subjunctive mood, suggesting purpose or potential. John’s writing has the purpose of leading the reader to believe. The idea is that the testimony in John’s Gospel is designed to bring faith into the hearts of the readers.
3. "That Jesus is the Christ, the Son of God" (ὅτι Ἰησοῦς ἐστιν ὁ Χριστός, ὁ Υἱὸς τοῦ Θεοῦ)
This phrase is identical to the content of 1 John 5:1, affirming that faith in Jesus as the Christ is the essential truth for salvation. By believing this testimony, one participates in the saving work of Christ.
John emphasizes that the believer’s faith is not just in Jesus as a historical figure, but in His divine nature as the Messiah and the Son of God.
4. "That believing ye might have life through his name" (ἵνα ἐν τῷ ὀνόματι αὐτοῦ ζωὴν ἔξητε)
The verb "might have" (ἔξητε, exēte) is in the subjunctive mood, indicating the potential result of belief. Eternal life is the result of faith in Jesus. The name of Jesus here symbolizes His identity and authority. By faith in His name, the believer is granted life (zoē), which, in Johannine theology, refers to eternal life (John 17:3).
The written word of God (the Gospel) is not just for knowledge but for the purpose of producing faith in Jesus as the Christ.
Through believing this testimony, the believer receives life—eternal life through Jesus’ name, emphasizing faith as the means of salvation.

Summary:
Both 1 John 5:1 and John 20:31 establish that faith in Jesus as the Christ is the foundational truth of salvation. Faith is the means by which we receive eternal life—faith that Jesus is both the Messiah and the Son of God. The Johannine writings underline that believing this truth leads to being born of God and receiving life through Christ. Through the testimony of Scripture, believers come to a living faith that brings about salvation and eternal life.
