Henry At His Best First, this sermon is inaccurately marked for scripture reference. It has nothing to do with Isaiah 1:18.
The correct scripture references are Isaiah 45:23 & Philippians 2:9-11.
The subject matter is Christ's call to the unconverted. Speaking to those who can hear. How thankful we should be EVERY DAY that Christ chose each one of us. How so very blessed we are in just that alone.
