New Defender's Study Bible Notes
32:17 nothing too hard. God, being omnipotent, simply called into existence the infinite expanse of the heaven and the infinite complexity of the earth. There is nothing too hard (same word as “wonderful”) for Him to accomplish (Genesis 18:14; Luke 1:37). The concept of instantaneous, perfect creation by Almighty God is far more reasonable than that of a billion-year trial-and-error naturalistic evolutionary growth from primeval chaos to the complex cosmos and its inhabitants.
32:27 too hard. God thus confirms Jeremiah’s statement of faith in His omnipotence (Jeremiah 32:17).
