Calvinist thinkers: What do you think about God loving those who do not believe, and will perish?

God loves even those who do not believe... actually salvation was made available to everyone. Its just not all were willing to avail of God's offer of salvation. Despite given all the chance, they chose to remain in their wicked ways and turn away from the Light. But remember also that God is righteous and just. Yes he loves those who do not believe but it is not righteous if he would leave justice not served. And because the punishment due for disbelief is hell, it is but proper to cast them into the lake of fire.
