Someone shouldn't go to church for the purpose of meeting someone else, but for the purpose of worshipping God. But the church should care because that is the start of families- which God instituted. But there's a fine line- they should encourage looking for a godly mate, and having the traits of a godly mate, but not play matchmaker for two specific people to get to together.
Because making them feel like they should over-rides chemistry- which causes the love that bonds a marriage. You don't want them to marry out of a sense of duty. But what if someone goes to all these premarital classes and never gets married- isn't that setting them up for heartache?
They tried to start a singles group in a congregation I once attended. So I agreed to join, even though there was a guy in it I really did not like. It started with only three of us, but I thought maybe other congregations would join in, and maybe I'll meet someone.
So I was sitting down to dinner, with our super small singles group, and that guy I didn't like took my hand from across the table, and started to stroke it. I pulled my hand back, but he held it tightly and wouldn't let me go. I firmly said "Stop!" and pried my hand away. That was it for me and singles groups.
