It's important to resist that false 'faith only' argument, but not at the expense of the true 'faith only' argument in which a person is converted entirely on the basis of their faith in the forgiveness of sin through Jesus Christ.
Faith does not save you.
God saves you, through your faith, ONE TIME.........and the result of that, is "born again".
This happens ONCE in your life.
ONCE, in your life, you gave God your faith in Christ, and God accepted it to give you "the righteousness of God, in Christ".
This happens once...ONE TIME>..........and on that day, in that instant, you become a born again, Son of God, redeemed, as a "NEW CREATION in Christ".
This is not repeated.
This is not something that end, or changes.
Salvation is Christ on the Cross, and God accepting THAT SACRIFICE on your behalf.
You dont WORK for that, and you dont work to keep it.
You RECEIVE it, as "the Gift of Salvation"..
After that, you live the life of a Disciple, and that is those works you do, and so forth.
Understand, those works are not your Salvation........ JESUS is your Salvaiton.
John 14:6
