You can start over even if you’re not sure God loves you. You can start oven even if you’re not sure He should.
And you don’t have to run. You can shamble over resentfully. You can sidle in doubtfully. You can skulk in with fear, doubt, despair, or even rage. As long as you go because you’re acknowledging that things are not good as they are, then that is good enough. It may not feel like it is enough, but that is what Christ has promised.
