Psalm 119: 126. It is time for thee, Lord, to work: For they have made void thy law.
David was a servant, and therefore it was always his time to work: but being oppressed by a sight of man's ungodly behaviour, he feels that his Master's hand is wanted, and therefore he appeals to him to work against the working of evil. Men make void the law of God by denying it to be his law, by promulgating commands and doctrines in opposition to it, by setting up tradition in its place, or by utterly disregarding and scorning the authority of the lawgiver. Then sin becomes fashionable, and a holy walk is regarded as a contemptible puritanism; vice is styled pleasure, and vanity bears the bell. Then the saints sigh for the presence and power of their God: Oh for an hour of the King upon the throne and the rod of iron! Oh for another Pentecost with all its wonders, to reveal the energy of God to gainsayers, and make them see that there is a God in Israel! Man's extremity, whether of need or sin, is God's opportunity. When the earth was without form and void, the Spirit came and moved upon the face of the waters; should he not come when society is returning to a like chaos? When Israel in Egypt were reduced to the lowest point, and it seemed that the covenant would be void, then Moses appeared and wrought mighty miracles; so, too, when the church of God is trampled down, and her message is derided, we may expect to see the hand of the Lord stretched out for the revival of religion, the defence of the truth, and the glorifying of the divine name. The Lord can work either by judgments which hurl down the ramparts of the foe; or by revivals which build up the walls of his own Jerusalem. How heartily may we pray the Lord to raise up new evangelists, to quicken those we all early have, to set his whole church on fire, and to bring the world to his feet. God's work is ever honourable and glorious; as for our work, it is as nothing apart from him.
