The most likely Bible author of 1 Peter 3:18 is the apostle Peter. According to evangelical Christian perspective, Peter was one of the twelve disciples of Jesus and played a significant role in the early church. He was a bold and outspoken leader, and is often seen as the spokesman for the other disciples.

Evangelical Christians believe that Peter’s authorship of 1 Peter is supported by internal evidence within the book itself, as well as by early church tradition. In 1 Peter 5:1, the author refers to himself as “a fellow elder” and “a witness of the sufferings of Christ.” This aligns with what is known about Peter’s role as an elder in the church and his close relationship with Jesus during his ministry.

Additionally, early church fathers such as Irenaeus, Tertullian, and Origen all attributed the letter to Peter. While some scholars have questioned the authorship of 1 Peter, many evangelical Christians maintain that Peter was indeed the author and that the letter reflects his teachings and experiences.

From an evangelical Christian perspective, 1 Peter 3:18 is a powerful verse that speaks to the redemptive work of Jesus Christ. It states, “For Christ also suffered once for sins, the righteous for the unrighteous, that he might bring us to God, being put to death in the flesh but made alive in the spirit.” This verse is seen as a reminder of the sacrifice of Jesus on the cross for the forgiveness of sins and reconciliation with God, as well as a call to live in righteousness and faith.
