Without Divorce As An Option

It would absolutely be better to never marry, in either the legal or the true Biblical/relational sense (personal, mutual commitment) if divorce was never or almost never a morally legitimate option.  In spite of however much evidence there is that a person is or would make for a great spouse, there is always the possibility, as long as one has these human epistemological barriers, that this is an illusion.  Marriage is already an enormous commitment.  Without divorce ever being a permissible direction to go in for at least some circumstances, it would be an even more uncertain gamble on whether one would wind up in a horrendous, mediocre, or excellent marriage.

The only mind one can know the existence or contents of is one's own.  No being with my limitations knows the future, and there is scarcely anything a person can truly control.  They do not know if their partner is rational, honest, loving, or sincere, only that they appear that way, and there is nothing at all impossible about them suddenly changing for the worst or revealing that their true self scarcely resembled the facade.  A person who seemed otherwise can unveil assumptions, hypocrisy, greed, unfaithfulness, pettiness, jealousy, or other kinds of irrational or immoral traits--or they could acquire these characteristics only after the marriage starts.

What careless person who truly knows these things would ever think marriage should be treated anything other than an almost total gamble that, on a personal and pragmatic level, could not possibly be worth the potential risk of a lifetime of suffering?  Just having an escape possibility, and a potentially morally valid one at that, makes heading into a marriage so much less suffocating and restricting.  There is the logical possibility of ending a marriage and the moral freedom to do so if it is marred by abusive, neglectful, adulterous, or other behaviors (yes, according to the Bible [1]).  Apart from this, human marriage would never truly be liberating or empowering, and every spouse would be locked into their relationships anyway.

Without divorce as an option, only in extremely rare relationships between rationalistic couples--and even then, this could be rare among them--would entertaining the desire to marry be anything more than an utterly pointless or damaging thing.  Marriage is not necessarily objectively good or subjectively fulfilling, and divorce, as unfortunate as it is that any relationship would need to come to it, is certainly worthwhile in more cases than evangelicals would admit.  To marry is not to Biblically remain fastened to someone no matter how philosophically stupid, how morally unstable, or how predatory or selfish they are.  Again, why would anyone ever want to marry if this was the case when marriage itself is not obligatory?
