This is an unhappy expression, bringing in the name of God where it does not occur. In the O.T. it is chalilah, 'far be it.' Ge 44:7,17, etc. In the N.T. ?? ???????, 'let it not be.' Ro 3:4,6,31, etc.
the faithfulness of God of no effect? by no means; yea, let God be acknowledged to be true, tho' men should be all deceivers; as it is written, " that you might be justified in your sayings, and might overcome when you are judged."
not at all: for then how could God judge the world?
do we then make the law useless by our doctrine of faith? by no means; on the contrary, it is we that observe the law.
