Q. What is a reprobate according to scripture? How does one become a reprobate? Can a Christian become reprobate?
A. The Greek word translated “reprobate” comes from metal working and describes something that does not meet the test, or is not approved, due to impurities or imperfections. When used of humans it often describes the flawed thinking of unbelievers, as in Romans 1:28.
A Christian cannot become reprobate because our faith in the Lord’s sacrifice on our behalf has made us perfect forever in God’s sight (Hebr. 10:12-14). He sees us as a new creation (2 Cor. 5:17) as righteous as He is (2 Cor. 5:21) without stain or wrinkle or any other blemish, but holy and blameless (Ephes. 5:27).
