Ezra's aim in leading the expedition may be gathered from the reflection of it in the royal edict, since that edict was doubtless drawn up with the express purpose of furthering the project of the favoured Jew. Ezra puts the beautifying of the temple in the front of his grateful words of praise to God. But the personal commission entrusted to Ezra goes much further. The decree significantly recognises the fact that he is to carry up to Jerusalem a copy of the Sacred Law. It refers to "the law of thy God which is in thine hand."[87] We shall hear more of this hereafter. Meanwhile it is important to see that the law, obedience to which Ezra is empowered to exact, is to be conveyed by him to Jerusalem. Thus he is both to introduce it to the notice of the people, and to see that it does not remain a dead letter among them. He is to teach it to those who do not know it.[88] At the same time these people are distinctly separated from others, who are expressly described as "all such as know the laws of thy God."[89] This plainly implies that both the Jerusalem Jews, and those west of the Euphrates generally, were not all of them ignorant of the Divine Torah. Some of them, at all events, knew the laws they were to be made to obey. Still they may not have possessed them in any written form. The plural term "laws" is here used, while the written compilation which Ezra carried up with him is described in the singular as "The Law." Ezra, then, having searched out The Law and tested it in his own experience, is now eager to take it up to Jerusalem, and get it executed among his fellow-countrymen at the religious metropolis as well as among the scattered Jews of the provincial districts. His great purpose is to make what he believes to be the will of God known, and to see that it is obeyed. The very idea of a Torah implies a Divine will in religion. It presses upon our notice the often-forgotten fact that God has something to say to us about our conduct, that when we are serving Him it is not enough to be zealous, that we must also be obedient. Obedience is the keynote of Judaism. It is not less prominent in Christianity. The only difference is that Christians are freed from the shackles of a literal law in order that they may carry out "the law of liberty," by doing the will of God from the heart as loyal disciples of Jesus Christ, so that for us, as for the Jews, obedience is the most fundamental fact of religion. We can walk by faith in the freedom of sons; but that implies that we have "the obedience of faith." The ruling principle of our Lord's life is expressed in the words "I delight to do Thy will, O My God," and this must be the ruling principle in the life of every true Christian. [87] Ezra vii. 14.
