Both the parable of the tares and that of the net plainly teach that there is no time when all the wicked will turn to God. The wheat and the tares grow together until the harvest. The good and the bad fish are together drawn ashore for a final separation. (COL 123.1) MC VC

Again, these parables teach that there is to be no probation after the judgment. When the work of the gospel is completed, there immediately follows the separation between the good and the evil, and the destiny of each class is forever fixed. (COL 123.2) MC VC

God does not desire the destruction of any. “As I live, saith the Lord God, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live. Turn ye, turn ye from your evil ways; for why will ye die?” Ezekiel 33:11. Throughout the period of probationary time His Spirit is entreating men to accept the gift of life. It is only those who reject His pleading that will be left to perish. God has declared that sin must be destroyed as an evil ruinous to the universe. Those who cling to sin will perish in its destruction. (COL 123.3) MC VC
