Do I really need a firewall for my server? (sopuli.xyz)

I've been running my server without a firewall for quite some time now, I have a piped instance and snikket running on it. I've been meaning to get UFW on it but I've been too lazy to do so. Is it a necessary thing that I need to have or it's a huge security vulnerability? I can only SSH my server from only my local network and must use a VPN if I wanna SSH in outside so I'd say my server's pretty secure but not the furthest I could take it. Opinions please?

One thing that hasn't been said in this thread is the following: Do you trust your router? Do you have an isp that can probe your router remotely and access it? In those cases, you absolutely need a firewall

    Absolutely. Even if your ISP is firewalling, never trust they will maintain it, and some of these cheapshit routers they use are awful. Use your own router and put it on the ISP routers DMZ.
