66:5-14 The prophet turns to those that trembled at God's word, to comfort and encourage them. The Lord will appear, to the joy of the humble believer, and to the confusion of hypocrites and persecutors. When the Spirit was poured out, and the gospel went forth from Zion, multitudes were converted in a little time. The word of God, especially his promises, and ordinances, are the consolations of the church. The true happiness of all Christians is increased by every convert brought to Christ. The gospel brings with it, wherever it is received in its power, such a river of peace, as will carry us to the ocean of boundless and endless bliss. Divine comforts reach the inward man; the joy of the Lord will be the strength of the believer. Both God's mercy and justice shall be manifested, and for ever magnified.
