The Everlasting Covenant
No Change at Sinai
Therefore the entering of the law at Sinai could not contribute any new feature to the covenant made with Abraham and confirmed in Christ, nor could it in any way whatever interfere with the promise. The covenant, that was confirmed beforehand by God in Christ, cannot by any means be disannulled, or its promises made of none effect, by the law spoken four hundred and thirty years afterward.
