Scripture teaches that God is love (1 Jn 4:18). It is through God's love that we "live, and move, and have our being" (Act 17:28). God "wills everyone to be saved and come to knowlege of the truth" (1 Tim 2:4). Love never fails (1 Cor 13:8). "Neither death, nor life, nor angels, nor principalities, nor present things, nor future things, nor powers, nor height, nor depth, nor any other creature will be able to separate us from the love of God in Christ Jesus our Lord" (Rom 8:38-39).
Frankly, it is difficult to comprehend how an eternally all-knowing and all-powerful God, whose essence is perfect love, could or would ever abandon any of God's imperfect and finite human creatures to eternal separation from God, based on their lack of Christian baptism, or their unrepented or unconfessed acts or ommissions that occur during their relatively short lifetimes; especially when one considers this universe has been continually evolving for almost 14 billion years. That's not to say that humans are released from the consequences of their decisions, acts, or omissions committed during their lifetimes. One only needs to consider the concept of karma ("you reap what you sow") that we find in the teachings of Hinduism, Buddhism and other religious traditions, as well as the purpose of purgatory as taught in the Catholic Christian tradition. Moreover, there are those living today who, due to sickness, disability, poverty, hunger, violence, terror, war, addiction, or some other suffering, could consider themselves to be already experiencing sheer "hell" on earth.
We are reminded of the parable of the loving father, as an image of God, running out to welcome his lost son home and to embrace him, even before the son could confess and repent of his sins to his father (Luke 15:11–24). Would any loving parent ever give up on the hope that their child, who is similarly lost, will eventually come to their senses and return home? Why then would an unconditionally loving and eternal God ever give up on us merely because we physically died? Would not such a loving God continue to wait for any lost souls to return home to God regardless of how long it took? After all, God is eternal and nothing can separate us from the love of God!
