Isaiah 51:1, 2
Lest they should grow dejected at the low estate of the nation, they are bidden to remember whence it came. One man was chosen, and one woman, they were both old before a child was born to them, they were a lone family in the earth; yet out of them sprang a great nation; nothing could be more apparently hopeless, yet the covenant was fulfilled, and therefore the like could and would be done again, and poor, downtrodden Israel would yet arise.
God is faithful, and will be true to his covenant; it is no agreement for days and years, its tenure is everlasting. The salvation which this covenant promises shall not be hidden in a corner, afar off it shall be published, even as it is at this day in our own fair island of the sea. Nothing can be more delightful than to have this salvation in possession, and to see its stable foundation in the covenant of grace.
Fear not dying man, trust in the ever-living God.
Awake, awake, put on strength, O arm of the Lord; awake, as in the ancient days, in the generations of old. Art thou not it that hath cut Rahab or Egypt
and wounded the dragon? or the crocodile, the emblem of Egypt.
This is a bold prayer. It lays hold upon that glorious arm which wrought such marvels in Egypt on behalf of the Lord’s elect, and its plea is that he can do like deeds again, and that the time has come for him to do them.
Assured faith here quotes the promise which had been given in a previous prophecy, and confidently asserts that it will be ever so. It is always well to have a promise at our fingers’ ends.
Isaiah 51:12, 13
It is in God’s hands. No oppressor can rage against us unless the Lord permits; why then do we fear? He who gives our foe permission to annoy us in measure, holds the other end of his chain and will keep him within bounds. In holy confidence let us stand still and see the salvation of God.
Awake, all-conquering Arm, awake,
And Satan’s mighty empire shake;
Assert the honours of thy throne,
And make this ruin’d world thine own.
