Extended Author's Note
I am of the belief, (And, I am afraid, very stubborn about it), that only if a person truly did not love God, only then they would go to Hell. By what is apparent to me through meditation on the Passion and on the nature of Gods love for us, I do not see how I could believe otherwise.
For all sins may be forgiven, (Baring, of course blasphemy, against the Holy Spirit which is to refuse forgiveness), and their wages paid through Christ.
Now, it would seem that no atheist, agnostic or otherwise would be damned to Hell for they do not know God and thus are unable to love Him. This is plainly ridiculous.
God is not an entity to which a name can be attached and through that name be judged. Those who hate God for what they suppose He is will, inevitably either now or later, find that this supposed entity that they hate does not in truth exist.
God is, (for lack of a better word), a force. The, (For there can only be one), Infinite and Supreme Force that is Goodness and Love. So it is apparent that anyone who hates a supposed god who supposedly inflicts upon his people unnecessary harm, do not truly hate God, but instead waste their energies upon nonexistence.
How then is God loved if not by His name? For God is not loved by words and thoughts, which only express feelings.
Love is God and thus anyone who truly loves has God within him. "God is Love, and who ever remains in Love remains in God and God in him." This is why we are to be judged on our actions for if we acted for the higher good of others, (Which is Love), and thus loved them and thus loved God, then shall we have Heaven. If it is found that we did not acted for others and thus did not love them and so did not love God, then shall we have chosen Hell, the eternal separation from the One who we do not love but who loves us.
"If anyone says, 'I love God,' but hates his brother, he is a liar; for whoever cannot love his brother who he has seen cannot love God who he has not seen. This is the commandment we have from Him: whoever loves God must love his brother."
So in conclusion, and in accordance with my own belief, if anyone were to love God, (Regardless of any of who they are and what they believe), they would be counted among his followers on the last day. As shown in the poem.
