So, dear brethren, to gather all up in a sentence, let us confidently look for times of blessing, penitently acknowledge that our own faithlessness has hindered the arm of the Lord, earnestly beseech Him to come in His rejoicing strength, and, drawing ever fresh power from constant communion with our dear Lord, use it to its last drop for Him. Then, like the mortal leader of Israel, as he pondered doubtingly with sunken eyes on the hard task before his untrained host, we shall look up and be aware of the presence of the sworded angel, the immortal Captain of the host of the Lord, standing ready to save, 'putting on righteousness as a breastplate, an helmet of salvation on His head, and clad with zeal as a cloak.' From His lips, which give what they command, comes the call, 'Take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.' Hearkening to His voice, the city of the strong ones shall be made an heap before our wondering ranks, and the land shall lie open to our conquering march. Wheresoever _we_ lift up the cry, 'Awake, awake, put on strength, O arm of the Lord,' there follows, swift as the thunderclap on the lightning flash, the rousing summons, 'Awake, awake, put on thy strength, O Zion; put on thy beautiful garments, O Jerusalem!' Wheresoever it is obeyed there will follow in due time the joyful chorus, as in this context, 'Sing together, ye waste places of Jerusalem; the Lord hath made bare His holy arm in the eyes of all the nations, and all the ends of the earth have seen the salvation of our God.' A PARADOX OF SELLING AND BUYING 'Ye have sold yourselves for nought; and ye shall be redeemed without money.'--ISAIAH iii. 3. THE first reference of these words is of course to the Captivity. They come in the midst of a grand prophecy of freedom, all full of leaping gladness and buoyant hope. The Seer speaks to the captives; they had 'sold themselves for nought.' What had they gained by their departure from God?--bondage. What had they won in exchange for their freedom?--only the hard service of Babylon. As Deuteronomy puts it: 'Because thou servedst not the Lord thy God with joyfulness... by reason of the abundance of all things, therefore shalt thou serve thine enemies...in want of all things.' A wise exchange! a good market they had brought their goods to! In striking ironical parallel the prophet goes on to say that so should they be redeemed. They had got nothing by bondage, they should give nothing for liberty. This text has its highest application in regard to our captivity and our redemption. I. The reality of the captivity.
