The requirement for salvation is that you believe in Jesus, John 3:18.
Salvation is by faith alone, because salvation is by Christ alone.
Jesus said to the rich young ruler that if he kept the commandments of God he would be saved and enter into Eternal life! Well those Christ lived and died for have kept the commandments of God by Christ doing it for them, they didn't do anything!
You missed it.
Jesus was trying to show the rich young ruler that he did not measure up to God's standards and that he was a sinner in need of a savior.
No one will be saved by keeping the commandments, because no one can keep the commandments. "All have sinned and come short of the glory of God", Romans 3:23.
Jesus Christ kept the commandments for them He lived and died for! You deny that Christ kept the commandments?
Only for those who have faith in him.
Calvinism is not of the faith. Your faith is misdirected.
