To believe in Jesus Christ is granted/given by grace Phil 1:29
29 For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake;
If something is given or granted to one,then its something naturally or originally they dont have. And the word given is the greek word χαρίζομαι:
to do something pleasant or agreeable (to one), to do a favour to, gratify
to show one's self gracious, kind, benevolent
to grant forgiveness, to pardon
to give graciously, give freely, bestow
to forgive
Its made of the greek word charis which is translated grace over 100 times in the NT
So to believe on Christ is bestowed as a Gift of Grace
So I believe I agree with the OP
