The faith I was reared in didn't require anybody to know anything. Just confess your sins and be saved, and there you were, safe in the arms of Jesus. A man could be too stupid to hit the floor with his hat . . . and yet he could be conclusively presumed to be one of God's elect, guaranteed an eternity of bliss, because he had been 'converted.' He might or might not become a Bible student; even that wasn't necessary . . . and he certainly didn't have to know, or even try to know, anything else.
