“I’ll never be as perfect as I supposedly should be. So why bother?.
That’s the whole point. You will NEVER be perfect. We are saved by grace, despite how rotten we are. The punishment we deserve for being far less than perfect was taken by Jesus on the cross. It is His gift to you. Take the gift. Embrace it. Tell everyone about it.
I didn’t feel that way when I went to church. Listening to sermons, it felt pretty useless to try. I’m not sure that’s how you should feel when you go to church.
