WHY WOULD A GOD NEED TO ASK....
Mark 8:23 And he took the blind man by the hand, and led him out of the town; and when he had spit on his eyes, and put his hands upon him, he asked him if he saw ought.
24 And he looked up, and said, I see men as trees, walking.
25 After that he put his hands again upon his eyes, and made him look up: and he was restored, and saw every man clearly.
Conclusion: Wouldn't a God know that the blind man needed more healing without asking.
Why would a God need to heal again as if there was no good results in the first.
