Eternal life has to do with two elements: being in God; and in an incorruptible physical body, termed a “spiritual body” (1Co 15:44, e.g. Luk 24:39). Thus the “resurrection” has solely to do with a new physical body, which all who come into this life will receive, the good and the evil (Jhn 5:28). All will be raised, some unto eternal life, and most unto eternal death (“second death” - Rev 2:11; 20:6, 14; 21:8); which the latter “shall be forever and ever” in “the lake of fire” (Rev 20:10).
Eternal life can only be given once, or it isn’t eternal life, because it is life in God—“forever.” If one were asking God for eternal life, wouldn’t He know if they were being sincere? Thus, to honor His Word He gives it only to those He knows who genuinely desire it. How could He do otherwise, knowing their insincerity? It’s insensible to conceive that He would give this gift knowing He would be taking it back due to the absence of truly desiring it.
Regardless of how hard it may seem, in knowing that God foreknows most will choose the “broad way” (Mat 7:13, 14), we can be confidently assured that all He does is “good” (e.g. Gen 1:4, 10, 12, 18, 21, 25, 31).
