We have an advocate

From James Durham's collection of 72 sermons on Isaiah 53 entitled Christ Crucified:

For your encouragement, consider that it is most advantageous and profitable. These words in the promise are broad and full, Whatsoever ye ask in my name, I will do it. And the promise is frequently repeated in these core cited chapters of John. O what calmness, tranquility, peace, victory over anxiety, what patience in waiting, whether when in bonds or liberty, do flow from the exercising of faith on this ground, to wit, that we have an advocate in heaven with the Father!
