For what if some did not believe? shall their unbelief make the faith of God without effect?
For what if some did not believe - or 'proved unfaithful.' It is the unbelief of the great body of the nation which the apostle points at; but as it sufficed for his argument to put the supposition thus gently, he uses this word "some" to soften prejudice.
Shall their unbelief make the faith of God without effect? - `invalidate,' or 'nullify, the faithfulness of God?'
