וְאֶת־רוּחִ֖י אֶתֵּ֣ן בְּקִרְבְּכֶ֑ם
וְעָשִׂ֗יתִי אֵ֤ת אֲשֶׁר־בְּחֻקַּי֙ תֵּלֵ֔כוּ וּמִשְׁפָּטַ֥י תִּשְׁמְר֖וּ וַעֲשִׂיתֶֽם
Ez 36:27, RSV. There is no disjunction here. What the spirit does is ensure that we keep the law.
"One might decide to suspend judgment about a given intellectual issue in dispute—and indeed prudence often dictated the advisability of such a course—for the sake of preserving concord in accordance with Christian caritas, for example, so that all that needed weighing could be weighed. But neither prudence nor the suspension of judgment nor the yearning for civility could get round the principle of noncontradiction: although two contrary claims might both be false, even the everlasting suspension of judgment could not make them both true."
