Galatians 5:5

For--proof of the assertion, "fallen from grace," by contrasting with the case of legalists, the "hope" of Christians. through the Spirit--Greek, rather, "by the Spirit": in opposition to by the flesh (Gal 4:29), or fleshly ways of justification, as circumcision and legal ordinances. "We" is emphatical, and contrasted with "whosoever of you would be justified by the law" (Gal 5:4). the hope of righteousness--"We wait for the (realization of the) hope (which is the fruit) of the righteousness (that is, justification which comes) by (literally, 'from--out of') faith," Rom 5:1, Rom 5:4-5; Rom 8:24-25, "Hope . . . we with patience wait for it." This is a farther step than being "justified"; not only are we this, but "wait for the hope" which is connected with it, and is its full consummation. "Righteousness," in the sense of justification, is by the believer once for all already attained: but the consummation of it in future perfection above is the object of hope to be waited for: "the crown of righteousness laid up" (Ti2 4:8): "the hope laid up for you in heaven" (Col 1:5; Pe1 1:3).
