To add the word "free" to the word "gift" is redundant. My KJV concordance does not have "free gift".
New International Version For it is by grace you have been saved, through faith--and this is not from yourselves, it is the gift of God--
Berean Literal Bible For by grace you are saved through faith, and this not of yourselves; it is the gift of God,
New King James Version For by grace you have been saved through faith, and that not of yourselves; it is the gift of God,
King James Bible For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
nternational Standard Version For by such grace you have been saved through faith. This does not come from you; it is the gift of God
John 4:10 Jesus answered, "If you knew the gift of God and who is asking you for a drink, you would have asked Him, and He would have given you living water."
Study Bible Alive with Christ …7in order that in the coming ages He might display the surpassing riches of His grace, demonstrated by His kindness to us in Christ Jesus. 8For it is by grace you have been saved through faith, and this not from yourselves; it is the gift of God, 9not by works, so that no one can boast.…
And so on and so on.
I agree: "charisma" means gift, which means it is free, though sometimes two words can reinforce a meaning, yet I never got in this debate. Thus I think you meant to respond to someone. "The rest of your post is simply more recourse to parroting propaganda in lie of an actual argument" refers to the Catholic adversary, not you, but whom I copied in to ping those who were engaged in debate with her(?).
