LOL, it was NOT a typo!
Clearly the context shows it was a typo.
“Think of it this way: Can we know Jesus without being able to read? Yes. Sure we can. ******But God gave us the Bible to know Him better. Thus, we know Jesus best when we use all that He gave us to know Him - and that includes the Bible naturally.******* [Actually, here’s another typo]: Yet no one would doubt that illiterate people can know Jesus just because they can[can’t] read. Any literate Christian person who has access to a Bible is making a mistake if they [don’t] spend time reading it. Any Catholic who has access to a priest but does *******not******* avail himself of God’s gift of absolution held by the priest is making a mistake.”
The context (i.e. “not” in “does not avail himself”) shows it was a typo. You can claim otherwise, but the truth is obvious from the context.
