It's broken! We shouldn't expect it to be comfortable, easy, or even to go smooth.
It's not how God created it to be. He created it perfect. We messed it up. Sin messed it up! It's cursed!
If you're talking to non-believing friends just ask them, "How's life going? Is it working like you thought it would?"
"No", would be the answer. It's not supposed to work here on earth apart from God. There's no peace or true joy without Christ.
Friends, it's broken. There's only one hope, one place to put our faith and trust and that's in Christ Jesus and Him crucified for all sin.
