Isaiah 41:20 says:

“That they may see and recognize
And consider and gain insight as well,
That the hand of the LORD has done this,
And the Holy One of Israel has created it.”

God’s miraculous works of ‘opening rivers in bare heights, of making the wilderness a pool of water, the dry land fountains of water’ (v.18). And of planting many varieties of fruitful plants in the desert (v.19) is for the very purpose of glorifying Himself!
