These simple words (or something like them), were prayed recently by one of the guys who is part of the church that I am a member of. They encapsulate one of the beautiful things about the Christian gospel. The apostle Paul wrote about it 2000 years ago..
'but God shows his love for us in that while we were still sinners, Christ died for us' Romans 5.8
It's such a relief. The gospel is indeed good news of what Christ has done and not merely good advice on how to live.
