WHAT EXACTLY IS A believer?

A‘believer’ is a child of God, born again by faith in Jesus Christ (see Acts 2:44); and an ‘unbeliever’ is someone who does not believe in Jesus. In the New Testament, the Greek word apistou is translated as ‘unbeliever.’ Its adjective form literally means ‘not faithful,’ and it describes someone who is lacking in Christian faith.

Christians are ‘set apart’

A believer is a child of God, born again by faith in Jesus Christ.

There is a clear distinction throughout Scripture between those who follow Christ The understanding was that those who had come to faith in Christ were in the process of being transformed into the image of Jesus (Rom 8:29). The further along they were in this process, the fewer similarities they had with unbelievers.
