"They shall mount up with wings as eagles." Isaiah 40:31

It is said of the eagle, that he mounts up towards the sun; and that of all birds, he is the only one which can gaze upon the sun with unshrinking eye. So with faith in the soul. The Lord's people alone can look by faith upon the "Sun of righteousness," gaze upon a glorious Immanuel at the right hand of the Father, and see a precious Jesus ever interceding for them, and drawing them near to his bosom. And when this blessed Jesus communicates a measure of his love and blood to their consciences, and raises up and draws forth faith in his name, then the soul begins to mount up with these wings like eagles, soaring higher and higher, till it comes into the presence of God; mounting up in higher and higher circles of spiritual flight, till it penetrates into the very sanctuary of Jehovah.

Now, has not your soul thus soared sometimes as upon eagle's wings? Have there not been those communications of divine life and light, those mountains of faith, those anchorings of hope, those goings forth of love, whereby your soul was enabled to mount up and find delight in Jesus, and felt his name, love, and blood precious? Have you not mounted up too, not only in the exercise of living faith and hope, but also of heavenly affection?

Sometimes we are so fastened down to this earth, this vale of tears, this waste-howling wilderness; so chained down to it, that we are like a bird with a broken wing, and cannot mount. We are swallowed up in the world, forgetting God and godliness. But are there not times and seasons when the soul is delivered from these chains and fetters, when earthly cares drop off from the mind, when our wings are new moulted, and fresh pinions as it were given, when the world and its temptations, sin and its snares are left behind, and there is a sweet mounting up in the feelings of heavenly affection? This is to "mount up with wings as eagles," and the soaring soul never ceases to mount till it comes into the very presence of the Three-One God of Israel.

"But they that wait upon the Lord shall renew their strength." Isaiah 40:31

How different the religion of a living soul is from the religion of a dead professor! The religion of a dead professor begins in self, and ends in self; begins in his own wisdom, and ends in his own folly; begins in his own strength, and ends in his own weakness; begins in his own righteousness, and ends in his own damnation. There is in him never any going out of soul after God, no secret dealings with the Lord, no actings of faith upon the divine perfections. But the child of God, though he is often faint, weary, and exhausted with many difficulties, burdens and sorrows; yet when the Lord does shew himself, and renews his strength, he soars aloft, and never ceases to mount up on the wings of faith and love till he penetrates into the very sanctuary of the most High.

A living soul never can be satisfied except in living union and communion with the Lord of life and glory. Everything short of that leaves it empty. All the things of time and sense leave a child of God unsatisfied. Nothing but vital union and communion with the Lord of life, to feel his presence, taste his love, enjoy his favour, see his glory—nothing but this will ever satisfy the wants of ransomed and regenerated souls. This the Lord indulges his people with. "They shall renew their strength." They shall not be always lying groaning on the ground, not always swooning away through the wounds made by sin, not always chained down by the fetters of the world, not always hunted in their souls like a partridge upon the mountains. There shall be a renewal of their strength; and in their renewal, "they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint."
