It is difficult to explain Hell when one can not accept the concept that we do not deserve Heaven, nor can we by anything of our own doing. Because we ourselves are corrupt and sinful, we do not deserve to behold God’s glory or to be in His presence whatsoever. That is, separation from God is a default. But because Christ personally intercedes for us, we are forgiven. But we also need to accept that forgiveness.
In other words, we of ourselves decide to take our inheritance and go our own way, and it is up to each of us to decide to go back home to our father. Surely, once he sees us on the road back from far away, he will run to us and embrace us and throw a party. But we are also free to be able to make the decision to be apostate. It’s our choice.
