Catholics dont rely on luck...but faith. Any man worth his salt in the day to day activities of his industry and growth will find himself with suitable ladys.
How? How is he going to find them if he doesn't go out and look for them? How will they know anything about him if they don't make the effort to meet one another?
good women are attracted to good men.
Women are also attracted to projects - men that they need to fix. Or senses of humor. Or a whole host of other things. Sometimes stable means "boring" to a young woman. Women have a lot of variance in what they want.
What about church aren't there eligible young ladys there?
Anyway...to say that leaving things happen in Gods time means...hoping to get lucky...you have a lot of faith maturing to do, which is why you dont have a bride yet.
Is God going to drop a meal in your lap if you don't go and seek out food? Is God going to give you a house if you don't go and get one yourself? No. You aren't going to get anything you don't work for, unless you luck into it, but that's the exception rather than the rule. In past times people didn't have this notion that people would just come across their perfect spouses by an act of God. Sometimes they arranged marriages to make good matches. Or they provided other means of getting young people together in their communities.
And sometimes it just doesn't happen. People don't get food and starve to death. They can't get houses and are homeless. They don't find spouses and are lonely for the rest of their lives. If you want to call that the will of God that we have to be resigned to, then fair enough, but that has no practical value whatsoever, because as long as I live I am going to do my best to get food and have a place to live, for example. I simply cannot do anything else, and it would in fact be wrong to do so, in my opinion.
