Q How can a wrong understanding of deterninism and predestination keep us from the kind of gusty prayers that moses prayed. What do you call a belief that our prayers makes no difference to God's response.
The belief that our prayes makes no difference to God,s response is not right because God is faithful and he has promised us that when we call him he will answers us and show us great things. In 2 kings 20:1-5 God had send prophet Isaiah to tell Hezekiah that he was not going to recover and he was going to die. Hezekiah prayed and God changed his response and added Hezekiah 15 more years.
