Temporal or spiritual—it is all the same. Everything temporal is also spiritual to God and to all those who are godly (D&C 29:34). The wicked or filthy cannot enter the kingdom of God because there cannot be anything filthy in a place where a totally clean Being lives. The wicked cannot enjoy the most precious and desirable fruit of the tree of life—the love of God that results in eternal life—which is the greatest of his gifts (D&C 6:13).
