"None lose you except those who depart from you." St. Augustine

Because God has blessed us with intellect and free will out of love and redeemed us out of love, God will always love us. That is his nature. Even when we forsake him as our God, going after other gods. While the light remains, when we depart from the light, we enter into darkness. Like the Prodigal Son, we can choose to deny and leave the Father, The Father always remains ready to receive us back. But if that is our last choice at the time of death, then we remain frozen in that choice. Still the Father loves u, even in accepting our free choice of darkness over the light.
