Mark 3:5 (NIV) says that Jesus looked around at them in anger and, deeply distressed at their stubborn hearts. Now, if God is ultimately responsible for condoning (Lamentations 3:37-38), could it be possible that Jesus was angry at whoever was responsible for allowing the Jewish leaders to be so stubborn? Could Jesus have been subconsciously angry at God for allowing the Jewish leaders to have such a close-minded corrupt way of thinking?
This is a perpetual question, "Is God responsible for all calamities and good things?". I would definitely answer "Yes". But wait, don't jump too fast your conclusion!
Let me first ask another question, "If you knew something bad was going to happen, and you knew how to intervene from its happening but you didn't take action. Do you think you should be responsible for the bad thing happened?"
The Lord took the ownership, not because He caused it, but He allowed it. Human borne to have different degree of disobedience. Our history were wars, killings, conspiracy, deception, everywhere without boundary. We should be grateful that the human race can survive until now, if not divine intervene at His time to restore the order.
Was God responsible for the Jewish Leaders their heart remained stubborn? Let's review these verses
Make the heart of this people calloused; make their ears dull and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed.” (Isaiah 6:10 NIV)
I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. (Ezekiel 36:26 NIV)
So yes, the Lord is responsible, and it is His sovereignty whether He let the evils remain evil (Isaiah 6:10), or save the penitent (Ezekiel 36:26).
However, if we realized we were in a calamity, there is a promise. For whoever see with their eyes, hear with their ears, understand with their hearts, turn and get the good things.
