This passage in Isaiah 41 was a great source of comfort to my heart. In the midst of the duties of the day, I found myself continually meditating on all that it contained. As the day drew to a close I happened to pick up my copy of Spurgeon's "Morning and Evening." I don't read it every day but I do pick it up and peruse its contents on occasion. Turning to the index I discovered that he had an entry on Isaiah 41:10. It is pertinent and I want to share it.
"God has a strong reserve with which to discharge this engagement; for He is able to do all things. Believer, till you can drain dry the ocean of omnipotence, till you can break into pieces the towering mountains of almighty strength, you never need to fear.
Think not that the strength of man shall ever be able to overcome the power of god. While the earth's huge pillars stand, you have enough reason to abide firm in your faith. The same God who directs the earth in its orbit, who feeds the burning furnace of the sun, and trims the lamps of heaven, has promised to supply you with daily strength.
While He is able to uphold the universe, dream not that He will prove unable to fulfil His own promises. remember what He did in the days of old, in the former generations. Remember how He spoke and it was done; how He commanded, and it stood fast. Shall He that created the world grow weary? He hangs the world upon nothing; shall He who does this be unable to support His children? Shall he be unfaithful to His word for want of power? Who is it that restrains the tempest? Does not He ride upon the wings of the wind, and make the clouds His chariots, and hold the ocean in the hollow of His hand? How can He fail you?
When He has put such a faithful promise as this on record, will you for a moment indulge the thought that He has outpromised Himself, and gone beyond His power to fulfill? Ah, no! You can doubt no longer!
O you who are my God and my strength, I can believe that this promise shall be fulfilled, for the boundless reservoir of Your grace can never be exhausted, and the overflowing storehouse of Your strength can never be emptied by your friends or rifled by Your enemies."
