A believer is someone who follows Jesus.
In a literal sense it means the same as Christian, although that word has become so maligned and distorted that many true Christians prefer to call themselves Christ followers, followers of Jesus, or simply believers.
Key verse about Believer: Because of this, the rumor spread among the believers that this disciple would not die. But Jesus did not say that he would not die; he only said, “If I want him to remain alive until I return, what is that to you?” (John 21:23, NIV).
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 700-page website ABibleADay.com to encourage people to explore the Bible. His main blog and numerous books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
