If I had a dime for every fundie Christian who presented “Jesus” as the answer to Hard Solipsism, I’d never have to work for money again. A few examples:

The fundamental problem, of course, is that the infallibility of God is irrelevant, never mind if it’s true. Even if an infallible God existed, putting your faith in him is still your own choice, and, therefore, subject to your own fallibility.
Even if you have completely purged yourself of doubt (I suspect, but cannot prove, that this is a lie), you can’t justify that. Your divine revelation might be nonsense from the devil, or it might just be stale bread and moldy cheese. Your logical reasoning might have a mistake, or an incorrect premise. Your reading of the Bible might be incorrect, or whatever process you used to decide that it was infallible might be wrong. You might claim that these things are unlikely, but you cannot claim that they are impossible.
Of course, I have no perfect solution to Hard Solipsism, either, but I’m not gonna claim that I do have one. I am pretty sure, however, that you will never be able to solve it by appealing to anything or anyone outside yourself; as long as your senses and mental faculties are imperfect (which any Christian worth their Bible must believe), your ability to perceive the thing-or-person beyond yourself will always be in question no matter how infallible the thing-or-person itself is.
