Matthew Henry's Concise Commentary

66:8-12 The Lord not only preserves our temporal life, but maintains the spiritual life which he has given to believers. By afflictions we are proved, as silver in the fire. The troubles of the church will certainly end well. Through various conflicts and troubles, the slave of Satan escapes from his yoke, and obtains joy and peace in believing: through much tribulation the believer must enter into the kingdom of God.
