When we consider our circumstances we so easily forget who the Lord is, we allow our thoughts to be concerned solely with whatever is facing us. The difficulties of the situation, how we got into the mess, why it is impossible to get out of it etc. We need to remind ourselves of who our God is.
The whole earth is as nothing to God. He can hold all the seas in the hollow of His hand, or hold the dust of the earth in a basket. This is, of course, figurative language, but the meaning is clear. God is infinitely greater than anything we face.
The Spirit of the Lord is wiser than all the wisdom of the world. The world has nothing to teach God, despite what it might think! The Lord has complete understanding and needs no-one to instruct Him.
The nations, which opposed Israel, are as nothing to God. When it says God regards them as nothing and worthless it does not mean that He does not care for the nations, but when they oppose Him it is no contest.
The nations had idols, but these were mere man-made things. They had no power of their own.
We need fear nothing, but should look to God in all circumstances.
