Charles H. Spurgeon on Psalms 135:6

Whatsoever the LORD pleased, that did he, etc. He was not forced to make all that he made, but all that he willed he made. His will was the cause of all things which he made. Thou makest a house, because if thou didst not make it thou wouldest be left without a habitation: necessity compels thee to make a home, not free will. Thou makest a garment, because thou wouldest go about naked if thou didst not make it; thou art therefore led to making a garment by necessity, not by free will. You plant a mountain with vines, you sow seed, because if thou didst not do so, thou wouldest not have food; all such things thou doest of necessity. God has made all things of his goodness. He needed nothing that he made; and therefore he hath made all things that he willed. He did whatsoever he willed in the heaven and earth: do you do all that you will even in your field? You will many things, but can not do all you wish in thy own house. Thy wife, perchance, gainsays thee, thy children gainsay thee, sometimes even thy servant contumaciously gainsays thee, and thou doest not what thou wiliest. But thou sayest, I do what I will, because I punish the disobedient and gainsayer. Even this you do not when you will. —Augustine.
