It isn’t a type-o. It is a revelation… at least for me it
was.
“For I long to see
you, that I may impart unto you some spiritual gift, to the end ye may be established; That is, that I may
be comforted together with you by the mutual faith both of you and me.”
Romans 1:11-12
The word translated in the King James as may
be established is stērizō.
It sounds like stereo because it is like it. In fact stereos (in
the Greek) is a synonym for it.
Everything sounds
better in stereo than it does through one speaker only.
And that is what
Paul is getting at.
