Thought from Today's Old Testament Passage:
[Isaiah 18:1-7] Here is the assurance God gives to his prophet, by him to be given to his people, that, though he might seem for a time to sit by as an unconcerned spectator, yet he would certainly and seasonably appear for the comfort of his people and the confusion of his and their enemies (v. 4): So the Lord said unto me. Men will have their saying, but God also will have his; and, as we may be sure his word shall stand, so he often whispers it in the ears of his servants the prophets. When he says, I will take my rest, it is not as if he were weary of governing the world, of as if he either needed or desired to retire from it and repose himself; but it intimates that the great God has a perfect, undisturbed, enjoyment of himself, in the midst of all the agitations and changes of this world (the Lord sits even upon the floods unshaken; the Eternal Mind is always easy), and, though he may sometimes seem to his people as if he took not wonted notice of what is done in this lower world (they are tempted to think he is as one asleep, or as one astonished, Ps. 44:23; Jer. 14:9), yet even then he knows very well what men are doing and what he himself will do.
