Jesus is well acquainted with failure and sin and faithlessness and betrayal and ugliness of all sorts. He knows all about it and is really good with it. . .and with us who fall into it. No matter how you are today, no matter how bad your experience, He is what you want. He is the solution. He is the way forward.
He may not answer all your questions, but He will give you life. And that's the real issue.
