Unless one is baptized (by water, desire, or blood) there will not be the Beatific Vision after death, because there will not be a state of sanctifying grace present. Adam and Eve were given the initial state of sanctifying grace, which we are not.
St. John Chrysostom, Baptismal Instruction. (Ancient Christian Writers, p. 57)
3:6"You have seen how numerous are the gifts of baptism. Although many men think that the only gift it confers is the remission of sins, we have counted its honors to the number of ten. It is on this account that we baptize even infants, although they are sinless, that they may be given the further gifts of sanctification, justice, filial adoption, and inheritance, that they may be brothers and members of Christ, and become dwelling places of the Spirit."
12:6: “You are called faithful both because you believe in God and have as a trust from him justificaton, sanctity, purity of soul, filial adoption, and the kingdom of heaven.”
