Divorce creates further barriers to reconciliation. While we are not discussing separation here, we can readily see that Paul instructs towards reconciliation, not away from it, even with unbelieving partners. And he also implies that divorce is like adding a padlock to the door through which an unfaithful partner has gone. Where reconciliation is the objective, divorce cannot be an option. Divorce perpetuates sin.
People choose divorce as an answer to their marriage problems.
But it is impossible to correct problems through disobedience to God. Divorce always creates more problems. No one can keep the consequences of sin to himself, and this seems especially true with divorce. Sin leads to sins, and those sins multiply in the generations to come. Studies have shown that those who come from divorced homes have a higher rate of divorce than those whose parents remained faithful.
