Yes, but only because most would assume that "accept" means "consent to receive (a thing offered)." Which definition does not define the salvation equation, as it assumes that one does not already have the thing "accepted." That's not how it works.
On the contrary, salvation is rather a matter of allowing one to define themselves by revealing just what it is they are made up of; meaning, if they are already "of God" or not. The biblical scriptures described this, as, "the man of sin is revealed", as manifesting in the flesh the things that are otherwise unseen and in the spirit.
In other words, it is as if we are born into this world to publicly empty or pockets to see if we have an entry token to the magic kingdom of eternal life. We either do or we don't. The "good news" however, is that even if we don't have what it takes--it's free for the asking. Thus, if one hears the first hand testimony that exists down throughout all of history from those who gave (and still give) their witness to what they have heard or seen of the truth of God, and believe it enough to see where it will take them, it's enough, and the doors will be opened to us.
It's not a challenge issue, but the doors of the heavens do not open to those who do not believe. In which case it all remains brilliantly out of sight and out of reach. Either way, whether only natural or spiritual, life is a gift. The one is simply and ultimately just smaller than the other.
