This farm is preserved by the Lord's continual _protection_. Not only did he enclose it, and cultivate it by his miraculous power, to make it his own farm, but he continually maintains possession of it. "I the Lord do keep it; I will water it every moment: lest any hurt it, I will keep it night and day." If it were not for God's continual power her hedges would soon be thrown down, and wild beasts would devour her fields. Wicked hands are always trying to break down her walls and lay her waste again, so that there should be no true church in the world; but the Lord is jealous for his land, and will not allow it to be destroyed. A church would not long remain a church if God did not preserve it unto himself. What if God should say, "I will take away the hedge thereof, and it shall be eaten up; and break down the wall thereof, and it shall be trodden down"? What a wilderness it would become. What saith he? "Go ye now unto my place which was in Shiloh, where I set my name at the first, and see what I did to it for the wickedness of my people Israel." Go ye to Jerusalem, where of old was the city of his glory and the shrine of his indwelling, and what is left there to-day? Go ye to Rome, where once Paul preached the gospel with power: what is it now but the centre of idolatry? The Lord may remove the candlestick, and leave a place that was bright as day to become black as darkness itself. Hence God's farm remains a farm because he is ever in it to prevent its returning to its former wildness. Omnipotent power is as needful to keep the fields of the church under cultivation as to reclaim them at the first.
