1 John 5:1 by Pastor John Samson
"Everyone who believes that Jesus is the Christ has been born of God." - 1 John 5:1
In the original Greek, the verb tenses in this verse are very revealing. A literal translation reads as follows: "All the ones going on believing (pisteuon, a present tense, continuous action) that Jesus is the Christ has been born (gennesanta, perfect tense - an action already complete with abiding effects) of God." The fact that someone is presently going on believing in Christ shows that they have first been born again. Faith is the evidence of regeneration, not the cause of it. Since both repentance and faith are possible only because of the work of God (regeneration), both are called the gift of God in scripture (Eph. 2:8, 9; Phil. 1:29; 2 Tim 2:24-26).
"Regeneration is the spiritual change wrought in the heart of man by the Holy Spirit in which a person's inherently sinful nature is so radically impacted, his disposition so affected, his mind so illumined, his will so liberated that a person can and will respond to God in saving faith and willingly live in accord with the will of God." - J. I. Packer
