“Yahweh, You are my God; I will exalt You. I will praise Your Name, for You have accomplished wonders, plans formed long ago, with perfect faithfulness.” (Isaiah 25: 1, Holman Christian Standard Bible)
Why is anyone surprised or bewildered that God plans? Why are we taken aback by God having created us knowing we would fall, having allowed the serpent to tempt us, having driven us from Eden, having planned our salvation? Why does it irk us that God makes choices? Is He not in complete control? Is He not sovereign? Does He not have the final say in any matter?
“For who has known the mind of the Lord? Or who has been His counselor? Or who has ever first given to Him, and has to be repaid?” (Romans 11: 34 – 35)
The way around bewilderment or even resentment that God is in control is to recognize that everything He does is done “with perfect faithfulness.” In God’s sovereignty there is no error.

what great surprise then when we submit to Him (and His perfect plan) and resist the devil we will also be likewise without error.
