“[I]t is the law which the heretical minds Paul is opposing in this letter are putting into competition with the promise — at bottom, in fact, they are placing it above the promise. It is by this opposition, this contrast, that the character of Paul’s conception of the covenant and the promise, yes, and of the law also, is entirely governed and determined. Law means demand, conditions; the promise, on the contrary, means free grant, guarantee, unconditionality.” (Herman N. Ridderbos, The Epistle of Paul to the Churches of Galatia, p. 135).

“Obedience as the appropriate and necessary expression of devotion to Christ does not find its place in a covenant of works or of merit but in a covenant that has its inception and end in pure grace.” (John Murray, Principles of Conduct, p. 200).
