There are benefits to staying single... such as being able to devote all your love and efforts to the Lord. That is where true freedom is.
I noticed as of this moment you haven't responded to the question about what freedom you refer to as the freedom of being single.
In my experience, that is usually a way for someone to say they want to live it up... live their life without any obligations or anything. As already stated, not the best of reasons to stay single.
I think our churches have an obsession with marriage, as if believers need to be married to be pleasing to God. If I had it to do over again I would never have gotten married. Not because I don't love my wife and kids, I absolutely do, but I would rather be able to devote my time and efforts to the Lord.
Don't feel like you have to get married, but do not avoid marriage so you can live immorally.
