Okay, I know the direct application of this verse is Jesus basically reiterating that He is the Way, the Truth, and the Life. He is the "sheepgate" and false prophets are the "thieves and marauders" He speaks of.
But there has been another way I have applied this verse in my own mind, namely regarding those who enter into non-marital unions (whether straight cohabitation, divorced and remarried without annulments*, or homosexual relationships), then turn around and want the rights of a married couple who did things the right way.
It seems these days the people who "if it feels good do it," who believe "better to ask forgiveness than permission" (and don't really ask forgiveness either, but just expect everyone else to give their blessing, are spitting in the eyes of the people who are trying to follow God's law. They want to join the club but they refuse to pay the dues for membership.
I'm sorry, but I've been celibate for decades rather than violate God's laws, and yet these "thieves and marauders" want the benefits of two incomes and social and religious recognition by virtue of some sort of "squatters' rights" approach to marriage.
I believe in mercy for those who recognize they've made mistakes - like a couple invalidly married who are trying to pursue an annulment or something - but I do get tired of people who just grab what they think they're entitled to. It cheapens the sacrifice that those of us who live chastely make. At least in the eyes of the world it does.
I guess we will get our reward in the Kingdom of Heaven, if we can try not to be angry. Seriously, I really do struggle with this. It's like being the older sister if the Prodigal Son parable were about two girls, and my younger sister not only went off and lived the life of a drunken sl** but is planning to continue and our mom throws her a big party.
*at least if they have been taught the Catholic way and know what they're doing, or if they have had so many multiple marriages it's ridiculously obvious they aren't taking marriage seriously enough or they have "issues."
