The beloved disciple John wrote the Gospel of John, the three epistles I, II, and III John and Revelation. Reading I John again it is clear that his commitment to Jesus never got lukewarm. I John 2:22-23 says the liar denies that Jesus is the Christ. I John 4:2-3 says the Spirit of God acknowledges that Jesus came in the flesh, but a false spirit will not. I John 5:11-12 says life is in God’s Son. If one doesn’t have the Son, one doesn’t have life. The key to not becoming lukewarm is to keep one’s focus on Jesus.
